An efficient protocol for C-H condensation of hypervalent iodine compounds with arenes in fluoroalcs. was applied to the recyclable preparation of mesityl iodonium(III) salts. The electrophilicities of [hydroxy(tosyloxy)iodo]mesitylene [MesI(OH)OTs] and iodomesitylene diacetate [MesI(OAc)₂] were suitably enhanced in 2,2,2-trifluoroethanol. A series of nucleophilic aromatic compounds reacted smoothly with MesI(OH)OTs and MesI(OAc)₂ or in-situ hypervalent iodine(III) species, generated from iodomesitylene, to provide the target mesityl iodonium(III) salts in good yields at room temperature with broad functional group tolerance. This C-H condensation strategy merits high para-regioselectivities during the diaryliodonium(III) salt formation, but the major limitation in the case of low-reactive aromatic substrates is byproduct formation resulting from the self-condensation of the nucleophilic mesitylene ring in MesI(OH)OTs and MesI(OAc)₂. This study involved multiple reactions and reactants, such as Mesityl(p-tolyl)iodonium trifluoromethanesulfonate (cas: 1204518-02-4Electric Literature of C17H18F3IO3S).

Mesityl(p-tolyl)iodonium trifluoromethanesulfonate (cas: 1204518-02-4) belongs to iodide derivatives. In addition to tryptophan, indigo, and indoleacetic acid, numerous compounds obtainable from plant or animal sources contain the indole molecular structure. More than 200 indole derivatives have already been marketed as drugs or are under advanced stages of clinical trials.Electric Literature of C17H18F3IO3S

Palladium-catalyzed redox cascade for direct β-arylation of ketones was written by Huang, Zhongxing;Dong, Guangbin. And the article was included in Tetrahedron in 2018.Electric Literature of C17H18F3IO3S The following contents are mentioned in the article:

A full article about the detailed design and development of two palladium-catalyzed redox cascade methods that enable direct β-arylation of ketones was reported. Palladium-catalyzed ketone dehydrogenation, aryl-X bond activation and conjugate addition were merged into a redox-neutral catalytic cycle. Non-metal-based aryl electrophiles were used as both the oxidant and the aryl source. The β-arylation with aryl iodides was achieved site-selectively with Pd(TFA)₂/P(i-Pr)₃ as the precatalyst and AgTFA as the iodide scavenger. Both cyclic and linear ketones were reacted to give β-aryl ketones with excellent functional group tolerance. The β-arylation with diaryliodonium salts was realized without stoichiometric heavy metal additives, and proved to be redox-neutral. A wider substrate scope regarding aryl groups and ketones was obtained for the arylation with diaryliodonium salts, and the possible involvement of palladium nanoparticles as the active catalyst was examined and discussed. This study involved multiple reactions and reactants, such as Mesityl(p-tolyl)iodonium trifluoromethanesulfonate (cas: 1204518-02-4Electric Literature of C17H18F3IO3S).

Mesityl(p-tolyl)iodonium trifluoromethanesulfonate (cas: 1204518-02-4) belongs to iodide derivatives. Indole, first isolated in 1866, and it is commonly synthesized from phenylhydrazine and pyruvic acid, although several other procedures have been discovered.Indole was synthesized in moderate yield via an o-naphthoquinone catalyzed tandem cross-coupling of substituted aniline and benzylamine under aerobic oxidation conditions.Electric Literature of C17H18F3IO3S

The synthesis and properties of new polyimides (PIs) derived from 4,4′-bis(p-aminophenoxy)triphenylamine (APT) and N,N-bis[4-(4′-aminophenoxy)phenyl]aminopyrene (APPA) for memory device application is reported. The starting monomers were prepared from 4-iodophenol and 4-fluoronitrobenzene via etherification (giving 4-(4′-nitrophenoxy)iodobenzene) followed by amination with aniline or aminopyrene and final reduction of terminal nitro-group. Polyimides were synthesized by polycondensation of each monomer with hexafluoroisopropylidene-2,2-bis(phthalic anhydride) in dimethylacetamide. All PIs had electron-rich arylamine moieties combining flexible phenyl-ether linkages which provide polymers electron-donating properties to reduce driving voltage in a memory device. The PIs exhibited high thermal properties such as 10% weight loss temperature >500° and glass transition temperatures >250°. The effects of structure on the thermal, optical, and electrochem. properties of the PIs are described in detail.

From Synthetic Simplified Marine Metabolite Analogues to New Selective Allosteric Inhibitor of Aurora B Kinase was written by Juillet, Charlotte;Ermolenko, Ludmila;Boyarskaya, Dina;Baratte, Blandine;Josselin, Beatrice;Nedev, Hristo;Bach, Stephane;Iorga, Bogdan I.;Bignon, Jerome;Ruchaud, Sandrine;Al-Mourabit, Ali. And the article was included in Journal of Medicinal Chemistry in 2021.Application In Synthesis of 8-Bromo-3-iodoimidazo[1,2-a]pyridine The following contents are mentioned in the article:

Significant inhibition of Aurora B was achieved by the synthesis of simplified fragments of benzosceptrins and oroidin belonging to the marine pyrrole-2-aminoimidazoles metabolites isolated from sponges. Evaluation of kinase inhibition enabled the discovery of a synthetically accessible rigid acetylenic structural analog EL-228, whose structure could be optimized into the potent CJ2-150. Here we present the synthesis of new inhibitors of Aurora B kinase, which is an important target for cancer therapy through mitosis regulation. The biol. oriented synthesis yielded several nanomolar inhibitors. The optimized compound CJ2-150 showed a non-ATP competitive allosteric mode of action in a mixed-type inhibition for Aurora B kinase. Mol. docking identified a probable binding mode in the allosteric site “F” and highlighted the key interactions with the protein. We describe the improvement of the inhibitory potency and specificity of the novel scaffold as well as the characterization of the mechanism of action. This study involved multiple reactions and reactants, such as 8-Bromo-3-iodoimidazo[1,2-a]pyridine (cas: 1232038-69-5Application In Synthesis of 8-Bromo-3-iodoimidazo[1,2-a]pyridine).

Metabolically stable diphenylamine derivatives suppress androgen receptor and BET protein in prostate cancer was written by Yu, Jiang;Zhou, Peiting;Du, Wu;Xu, Ruixue;Yan, Guoyi;Deng, Yufang;Li, Xinghai;Chen, Yuanwei. And the article was included in Biochemical Pharmacology (Amsterdam, Netherlands) in 2020.Application In Synthesis of 2-Chloro-4-iodobenzonitrile The following contents are mentioned in the article:

Androgen receptor (AR) is a crucial driver of prostate cancer (PC). AR-relevant resistance remains a major challenge in castration-resistant prostate cancer (CRPC). Bromodomain and extra-terminal domain (BET) family are critical AR coregulators. Here, we developed several diphenylamine derivatives and identified compound 7d that disrupted the functions of AR and BET family in prostate cancer and exhibited favorable metabolic stability in vitro and high drug exposure in vivo. We showed 7d not only bound to AR, suppressed transactivation of wild-type AR (wt-AR) and the mutant that mediates Enzalutamide resistance, but also reduced c-Myc protein expression through BET inhibition. In addition, 7d inhibited the proliferation of AR-pos. PC cells with favorable selectivity and suppressed AR-V7-expressing VCaP and 22Rv1 xenografts growth in vivo. Collectively, these results indicate the potential of lead compound 7d as an orally available AR and BET inhibitor to treat CRPC and overcome antiandrogen resistance. This study involved multiple reactions and reactants, such as 2-Chloro-4-iodobenzonitrile (cas: 371764-70-4Application In Synthesis of 2-Chloro-4-iodobenzonitrile).

Copper-Catalyzed Cascade Cyclization of Indolyl Homopropargyl Amides: Stereospecific Construction of Bridged Aza-[n.2.1] Skeletons was written by Tan, Tong-De;Zhu, Xin-Qi;Bu, Hao-Zhen;Deng, Guocheng;Chen, Yang-Bo;Liu, Rai-Shung;Ye, Long-Wu. And the article was included in Angewandte Chemie, International Edition in 2019.SDS of cas: 349404-93-9 The following contents are mentioned in the article:

Catalytic cycloisomerization-initiated cascade cyclizations of terminal alkynes have received tremendous interest, and been widely used in the facile synthesis of a diverse array of valuable complex heterocycles. However, these tandem reactions have been mostly limited to noble-metal catalysis, and are initiated by an exo-cyclization pathway. Reported herein is an unprecedented copper-catalyzed endo-cyclization-initiated tandem reaction of indolyl homopropargyl amides, where copper catalyzes both the hydroamination and Friedel-Crafts alkylation process [e.g., I → II (85%)]. This method allows the practical and atom-economical synthesis of valuable bridged aza-[n.2.1] skeletons (n=3-6) with wide substrate scope, and excellent diastereoselectivity and enantioselectivity by a chirality-transfer strategy. Moreover, the mechanistic rationale for this novel cascade cyclization is also strongly supported by control experiments, and is distinctively different from the related gold catalysis. This study involved multiple reactions and reactants, such as 4-Bromo-N-(2-iodophenyl)benzenesulfonamide (cas: 349404-93-9SDS of cas: 349404-93-9).

4-Bromo-N-(2-iodophenyl)benzenesulfonamide (cas: 349404-93-9) belongs to iodide derivatives. In addition to tryptophan, indigo, and indoleacetic acid, numerous compounds obtainable from plant or animal sources contain the indole molecular structure. Due to this activity, the indole ring system has become an important component or intermediate in the synthesis of heterocycles.SDS of cas: 349404-93-9

Efficient N-arylation of azole compounds utilizing selective aryl-transfer TMP-iodonium(III) reagents was written by Koseki, Daichi;Aoto, Erika;Shoji, Toshitaka;Watanabe, Kazuma;In, Yasuko;Kita, Yasuyuki;Dohi, Toshifumi. And the article was included in Tetrahedron Letters in 2019.Product Details of 1204518-02-4 The following contents are mentioned in the article:

It was determined that diaryliodonium(III) triflates bearing a trimethoxybenzene (TMP) auxiliary 2,4,6-(OCH₃)₃C₆H₂I⁺Ar-OTf^– (Ar = Ph, 4-methylphenyl, 4-methoxyphenyl, 2-chlorophenyl, thiophene-3-yl) are more reactive than the reported selective aryl-transfer iodonium salts in the N-arylation of benzimidazoles I (R = H, 5-NO₂, 6-Me, 5-OMe, 5-C(O)OMe) and other types of azole compounds such as 1H-imidazole, 2-methyl-1H-imidazole and 1H-pyrazole under catalytic conditions. The TMP-iodonium(III) salts can thus effectively facilitate the reaction at 50 °C or below, producing the corresponding N-arylated biaryls, e.g., II without the formation of TMP-derived coupling byproducts. Utilization of this TMP reagent under mild conditions would prevent the underlying problem of participation of the auxiliary group in the coupling reactions, which are observed while using the iodonium(III) salts that require elevated temperatures This study involved multiple reactions and reactants, such as Mesityl(p-tolyl)iodonium trifluoromethanesulfonate (cas: 1204518-02-4Product Details of 1204518-02-4).

Alternative ways of preparing nonracemic 2-amino[6]helicene derivatives were explored. The enantioselective [2 + 2 + 2] cycloisomerization of a nonchiral triyne under Ni(cod)₂/(R)-QUINAP catalysis delivered the enantioenriched (+)-(P)-2-aminodibenzo[6]helicene derivative in 67% ee.

And the article was included in Advanced Synthesis & Catalysis in 2015.Synthetic Route of C17H18F3IO3S The following contents are mentioned in the article:

The direct and regioselective copper/S-Phos-catalyzed trifluoromethylthiolation of sym. and unsym. di(hetero)aryl-λ³-iodanes has been accomplished for the synthesis of various (hetero)aryl trifluoromethyl sulfides employing readily accessible silver trifluoromethylthiolate (AgSCF₃) as nucleophilic trifluoromethylthiolating reagent. The developed transformation tolerates various functional groups like nitrile, enolizable ketone, ester, nitro and free carboxylic acid. Interestingly, the formal trifluoromethylthiolation of arenes was also achieved through integration of the synthesis of diaryl-λ³-iodanes from arenes with the trifluoromethylthiolation. Mechanistic investigations did not favor the radical formation and SET pathway. Based on the variable temperature ¹⁹F NMR spectroscopy, isolation of the most relevant catalytic intermediate, and stoichiometric studies supported the Cu(I)/Cu(III) catalytic cycle, wherein the oxidative addition of diaryl-λ³-iodanes was assisted by the silver salt.
