  Iodine-catalyzed Csp3-H functionalization of methylhetarenes: One-pot synthesis and cytotoxic evaluation of heteroarenyl-benzimidazoles and benzothiazole

  摘要：

  An efficient one-pot synthetic procedure has been developed for the preparation of heteroarenyl-benzim-dazoles via oxidative C-sp3-H functionalization with o-phenylenediamine using I-2-DMSO in open air from easily available starting materials. Based on a logical plan a spectrum of multi fundamental reactions like iodination, Kornblum oxidation and amination were brought into one-pot. By using this simple method a library of heteroarenyl-benzimidazoles derivatives (3a-t and 5a-g) and heteroarenyl-benzothiazole (3u) have been synthesized in good to excellent yield and screened for their cytotoxicity against a group of four human cancer cell lines. Among them 3h, 3q and 5b showed significant cytotoxic activities with an IC50 of 1.69, 1.62 and 2.81 mu M respectively against lung cancer (A549) cell line. (C) 2017 Elsevier Ltd.

  日期：——

  Organocatalytic functionalization of heteroaromatic N-oxides was investigated using in situ generated onium amide bases, and C-nucleophiles were efficiently introduced by the sequential addition–elimination reaction under metal-free conditions, affording 2-substituted nitrogen heteroaromatics generally in good to high yields.
