Design, synthesis, biological evaluation and molecular modelling studies of oxoacetamide warhead containing indole-quinazolinone based novel hybrid analogues as potential pancreatic lipase inhibitors was written by Auti, Prashant S.;Nandi, Arijit;Kumari, Vijeta;Paul, Atish T.. And the article was included in New Journal of Chemistry in 2022.Synthetic Route of C7H6INO2 This article mentions the following:

A novel series of indolyl oxoacetamide-quinazolinone hybrid analogs (9aa-9df) were designed, synthesized, and evaluated for their in vitro pancreatic lipase (PL) inhibitory potential which may lead to efficient anti-obesity agents. All the synthesized hybrid analogs exhibited moderate to potent PL inhibitory activity (IC50 = 32.51 to 4.86 μM). Among all the analogs, 9ak, 9af, 9aj, and 9ah were found to have the most potent PL inhibitory activity (IC50 = 4.86, 5.73, 5.83, and 5.94 μM resp.), as compared to orlistat (IC50 = 0.86 μM). The most potent analogs 9af and 9ak were found to inhibit PL competitively with an inhibition constant (Ki) of 2.136, 1.648 μM. Furthermore, the docking study confirmed the binding of analogs 9ak and 9af (MolDock score of -161.25, -133.67 kcal mol-1) that exhibited docking interactions with important active site amino acids, namely Phe 77, Tyr 114, Ser 152, Arg 256, His 263, etc. Also, the anal. of analog 9ak and 9af in SeeSAR revealed the covalent inhibition of PL. In mol. dynamics simulations of 100 ns, the complex between each analog (9ak & 9af) and PL was found to be stable (RMSD < 1.5 Å). The present work highlights the importance of a hybrid drug design approach for the development of indole and quinazolinone containing hybrids as potential PL inhibitors.

These bond strengths correlate with the electronegativity of the halogen, decreasing in the order F > Cl > Br > I. This periodic order also follows the atomic radius of halogens and the length of the carbon-halogen bond.Synthetic Route of C7H6INO2

Visible-Light-Induced Radical Carbo-Cyclization/gem-Diborylation through Triplet Energy Transfer between a Gold Catalyst and Aryl Iodides was written by Zhang, Lumin;Si, Xiaojia;Rominger, Frank;Hashmi, A. Stephen K.. And the article was included in Journal of the American Chemical Society in 2020.Application In Synthesis of 4-Bromo-2-iodophenol This article mentions the following:

Gem-Diboronates I (X = O, S, NBoc; R¹ = H, halo, MeCO, MeO₂C, ^tBu, CF₃, MeSO₂NH; R² = H, Me, Et; R³ = H, Me, ⁱPr, Bu) were prepared by photochem. diboration of propargylic substrates 2-I-R¹C₆H₃XCHR³CCR² with B₂pin₂ catalyzed by gold complex [Au₂(μ-dppm)₂(OTf)₂] with up to 90% yields. Geminal diboronates have attracted significant attention because of their unique structures and reactivity. However, benzofuran-, indole- and benzothiophene-based benzylic gem-diboronates, building blocks for biol. relevant compounds, are unknown. A promising protocol using visible light and aryl iodides for constructing valuable building blocks, including benzofuran-, indole- and benzothiophene-based benzylic gem-diboronates, via radical carbo-cyclization/gem-diborylation of alkynes with a high functional group tolerance is presented. The utility of these gem-diboronates has been demonstrated by a ten gram scale conversion, by versatile transformations, by including the synthesis of approved drug scaffolds and two approved drugs, and even by polymer synthesis. The mechanistic investigation indicates that the merging of the dinuclear gold catalyst (photoexcitation by 315-400 nm UVA light) with Na₂CO₃ is directly responsible for photosensitization of aryl iodides (photoexcitation by 254 nm UV light) with blue LEDs light (410-490 nm, λmax = 465 nm) through an energy transfer (EnT) process, followed by homolytic cleavage of the C-I bond in the aryl iodide substrates.

A reductive cross-coupling reaction of α-oxy halides, simply generated from aldehydes, with a series of C(sp²)- and C(sp)-electrophiles was reported. A wide range of aryl and heteroatom aryl halides, vinyl bromides, alkynyl bromides, and acyl chlorides react with unhindered and hindered aldehyde-derived α-oxy halides by providing protected alcs. as well as α-hydroxy ketones. Noteworthy, the reductive couplings are achieved not only through thermal catalysis with the use of metal reductants but also by photocatalysis, electrochem., and mechanochem. The unrestricted interchange of the four strategies indicates their underlying mechanistic similarities. The generation of NiI intermediate was proposed to be the key point for ketyl radical formation via a single-electron transfer (SET) event, which was rationalized by an array of control experiments and d. functional theory (DFT) calculations In the experiment, the researchers used many compounds, for example, 3-Iodobenzo[b]thiophene (cas: 36748-88-6Synthetic Route of C8H5IS).

P/N Heteroleptic Cu(I)-Photosensitizer-Catalyzed Deoxygenative Radical Alkylation of Aromatic Alkynes with Alkyl Aldehydes Using Dipropylamine as a Traceless Linker Agent was written by Bao, Hanyang;Zhou, Bingwei;Luo, Shu-Ping;Xu, Zheng;Jin, Hongwei;Liu, Yunkui. And the article was included in ACS Catalysis in 2020.Electric Literature of C8H5IS This article mentions the following:

A deoxygenative radical alkylation of aromatic alkynes with alkyl aldehydes for the preparation of allylarenes was successfully achieved. This transformation is accomplished through the reaction of alkyl aldehydes with alkynes in the presence of dipropylamine and Hantzsch ester catalyzed by a P/N heteroleptic Cu(I)-based photosensitizer under photoredox catalysis conditions. Preliminary mechanistic studies reveal that this aldehyde-alkyne coupling process comprises a regioselective radical addition of in-situ-generated alkyl-substituted α-amino radicals to alkynes with subsequent 1,5-proton transfer, C-N bond cleavage and concomitant isomerization of the resulting allyl radical species. Thus, in net result, dipropylamine serves as a traceless linker agent for the deoxygenative radical cross-coupling of alkyl aldehydes with alkynes under photoredox catalysis reaction conditions. In the experiment, the researchers used many compounds, for example, 3-Iodobenzo[b]thiophene (cas: 36748-88-6Electric Literature of C8H5IS).

3-Iodobenzo[b]thiophene (cas: 36748-88-6) belongs to iodide derivatives. Iodide-containing intermediates are common in organic synthesis, because of the easy formation and cleavage of the C–I bond. Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond.Electric Literature of C8H5IS
