Zhou, Zheng-Xin published the artcileCooperative Ligand-Promoted P(III)-Directed Ruthenium-Catalyzed Remote Meta-C-H Alkylation of Tertiary Phosphines, Formula: C5H9IO2, the publication is Organic Letters (2021), 23(6), 2057-2062, database is CAplus and MEDLINE.

Herein, the authors disclose a Ru-catalyzed meta-selective C-H activation of phosphines by using intrinsic P(III) as a directing group. 2,2,6,6-Tetramethylheptane-3,5-dione acts as the ligand and exhibits an excellent performance in boosting the meta-alkylation. The protocol allows an efficient and straightforward synthesis of meta-alkylated tertiary phosphines. Several meta-alkylated phosphines were evaluated for Pd-catalyzed Suzuki coupling and are superior to com. available ortho-substituted phosphines. The practicability of this methodol. is further demonstrated by the synthesis of difunctionalized phosphines.

A convenient and practical protocol was developed to synthesize glycosyl 1,3,4-oxadiazoles from D-glucosamine with good to excellent yields. The key step involved p-TsCl/pyridine-mediated cyclization under mild conditions. Subsequent removal of the acetyl groups in the last step, conducted using the system of NaOMe/MeOH, gave the desired N-acetyl-D-glucosamine 1,3,4-oxadiazole derivatives

Liu, Wei-wei published the artcileSynthesis, characterization, and biological evaluation of some novel glycosyl 1,3,4-thiadiazole derivatives as acetylcholinesterase inhibitors, Formula: C7H7IN2O, the publication is Heterocycles (2015), 91(2), 275-286, database is CAplus.

The corresponding 4-substituted glycosyl thiosemicarbazide derivatives were obtained by the reaction of glycosyl isothiocyanate with various hydrazides. Further cyclization with the system of p-TsCl/TEA led to the formation of N-glycosyl-5-substituted 1,3,4-thiadiazole-2-amine. Subsequent removal of the acetyl groups were conducted using the system of NaOMe/MeOH. The chem. structures of all new products were confirmed by IR, 1H NMR and ESI-HRMS. The acetylcholinesterase (AChE) inhibitory activities of those compounds were tested by Ellman’s method. Among them, the compound I possessed the best acetylcholinesterase-inhibition activity with IC₅0 of 18.38 ± 0.89 μM.

The UV spectra in 95% ethanol of all the synthesized cyanine dyes show that the photosensitization of the dyes increases (or decreases) by increasing (or decreasing) conjugation, by the presence of electron donating (attracting) groups and the more (less) planarity of the dyes. The new compounds have been identified by elemental anal. and IR and ¹H NMR spectral data.

A general practical approach to hetero(aromatic) and aliphatic P(O)Me₂-substituted derivatives is elaborated. The key synthetic step was a [Pd]-mediated C-P coupling of (hetero)aryl bromides/iodides with HP(O)Me₂. The P(O)Me₂ substituent was shown to dramatically increase solubility and decrease lipophilicity of organic compounds This tactic was used to improve the solubility of the antihypertensive drug prazosin without affecting its biol. profile.

Uegaki, Hiroko published the artcileLiving radical polymerization of acrylates with rhenium(V)-based initiating systems: ReO₂I(PPh₃)₂/Alkyl Iodide, Computed Properties of 31253-08-4, the publication is ACS Symposium Series (2000), 196-206, database is CAplus.

Rhenium(V) iododioxobis(triphenylphosphine) [ReO₂I(PPh₃)₂], a group 7 transition metal complex, induced living radical polymerizations of Me and Bu acrylates in conjunction with an iodide initiator such as CH₃CH(Ph)I and (CH₃)₂C(CO₂Et)I in the presence of Al(Oi-Pr)₃, where the reaction was faster than the NiBr₂(Pn-Bu₃)₂-mediated. The number-average mol. weights of the obtained polymers increased in direct proportion to monomer conversion, and the mol. weight distributions were relatively narrow throughout the polymerizations (M_w/M_n ∼ 1.6). The polymerization most probably proceeds via the rhenium-catalyzed homolytic cleavage of the polymer C-I terminal originated from the iodide initiator, as indicated by the ¹H NMR anal. of the polymer terminal structure and quenching study of the polymerization with a stable nitroxide radical. In contrast, a bromide initiator like CCl₃Br led to an uncontrolled acrylate polymerization with the rhenium(V) complex. The iodide/ReO₂I(PPh₃)₂ initiating system also induced a fast polymerization of Me methacrylate, though the polymerization was not controlled.

A convenient approach to assemble 1,2,3-triazole-fused 4 H-3,1-benzoxazines I (R = H, 6-Me, 7-I, 7,8-dimethoxy, etc.; R¹ = H, Me, Ph; R² = Bu, cyclopropyl, Ph, etc.) has been developed. Diverse alc.-tethered 5-iodotriazoles II (R³ = H, 6-Me, 5-I, 4,5-dimethoxy, etc.), readily accessible by a modified protocol of Cu-catalyzed (3+2)-cycloaddition, were utilized as precursors of the target fused heterocycles I. The intramol. C-O coupling proceeded efficiently under base-mediated transition-metal-free conditions, furnishing cyclization products I in yields up to 96%. Suppression of the competing reductive cleavage of the C-I bond was achieved by the use of Na₂CO₃ in acetonitrile at 100°C. This practical and cost-effective procedure features a broad substrate scope and valuable functional group tolerance.

In recent times, heterocyclic chemotypes are being explored for the development of new antimycobacterials that target the drug-resistant tuberculosis. Here, we are disclosing the 5-substitued 2-mercapto-1,3,4-oxadiazoles I (R₁ = Ph, 2-BrC₆H₄, 4-OHC₆H₄, etc.) as potent antitubercular agents. A small library of 2-mercapto-1,3,4-oxadiazoles I was synthesized using various acids. The compounds were evaluated for antituberculosis activity against M. tuberculosis H37Rv. Compound I (R₁ = 4-OHC₆H₄) was identified as antitubercular lead with MIC of 0.6μg/mL against M. tuberculosis H37Rv. This compound was nontoxic to CHO-K1 cells and showed selectivity index of 39. Of note, I (R₁ = 4-OHC₆H₄) showed antitubercular activity against pre-extensively drug-resistant clin. isolate of Mycobacterium with MIC of 2μg/mL. This study provides potent antitubercular agent which can be further optimized to discover novel antibiotics.
