Catalyst-Free Synthesis of 2-Arylbenzothiazoles in an Air/DMSO Oxidant System

摘要

A straightforward strategy for the synthesis of 2-arylbenzothiazoles from 2-aminothiophenol and aryl aldehydes in air/DMSO oxidant system has been developed. This reaction is operationally simple, proceeds without catalysts, tolerates a wide range of functionalities, and provides desired products in good to excellent yields.
