Palladium-Catalyzed Oxidative Sulfenylation of Indoles and Related Electron-Rich Heteroarenes with Aryl Boronic Acids and Elemental Sulfur

An efficient and convenient palladium-catalyzed C-H bond oxidative sulfenylation of indoles and related electron-rich heteroarenes with aryl boronic acids and elemental sulfur has been described. This procedure provides a useful and direct approach for the assembly of a wide range of structurally diverse 3-sulfenylheteroarenes with moderate to excellent yields from simple and readily available starting materials. Moreover, this synthetic protocol is suitable for N-protected and unprotected indoles. Notably, the construction of two C-S bonds in one step was also achieved in this transformation.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 1075-35-0, help many people in the next few years.1075-35-0

An Orally Bioavailable, Indole-3-glyoxylamide Based Series of Tubulin Polymerization Inhibitors Showing Tumor Growth Inhibition in a Mouse Xenograft Model of Head and Neck Cancer

A number of indole-3-glyoxylamides have previously been reported as tubulin polymerization inhibitors, although none has yet been successfully developed clinically. We report here a new series of related compounds, modified according to a strategy of reducing aromatic ring count and introducing a greater degree of saturation, which retain potent tubulin polymerization activity but with a distinct SAR from previously documented libraries. A subset of active compounds from the reported series is shown to interact with tubulin at the colchicine binding site, disrupt the cellular microtubule network, and exert a cytotoxic effect against multiple cancer cell lines. Two compounds demonstrated significant tumor growth inhibition in a mouse xenograft model of head and neck cancer, a type of the disease which often proves resistant to chemotherapy, supporting further development of the current series as potential new therapeutics.

Copper-catalyzed oxidative trimerization of indoles by using TEMPO to construct quaternary carbon centers: The synthesis of 2-(1 H -indol-3-yl)-2,3?-biindolin-3-ones

A simple, convenient, and efficient synthesis of 2-(1H-indol-3-yl)-2, 3?-biindolin-3-one derivatives has been developed by the oxidative trimeric reaction of indoles using the TEMPO/CuCl2 catalyst system under ambient air. This methodology provides an alternative approach for the direct generation of all-carbon quaternary centers at the C-2 position of indoles.

Sodium borohydride reduction of aldehydes catalyzed by an oxovanadium(IV) Schiff base complex encapsulated in the nanocavity of zeolite-Y

Selective reduction of a wide range of aromatic and aliphatic aldehydes to the corresponding alcohols with NaBH4 was achieved in the presence of an oxovanadium(IV) Schiff base complex encapsulated in the nanopores of zeolite Y (VOL-Y). For most of the aldehydes, a conversion of 100% was observed after less than 5 min. High chemoselectivity of the reduction for aldehydes over ketones was verified by a competitive reduction between 4-methylbenzaldehyde and acetophenone.

Synthesis of novel indole-benzimidazole derivatives

2-Methylindole-3-acetic acid and its 5-methoxy derivative were prepared from the respective phenylhydrazines and levulinic acid. Indole-3-carboxylic acid was obtained from indole, dimethylformamide and trifluoroacetic acid. These indole carboxylic acids were then condensed with substituted o-phenylenediamines under high temperature conditions in the presence of polyphosphoric acid as a catalyst to give the combined indole-benzimidazoles.
