CuI-catalyzed one-pot synthesis of benzothiazolones from 2-iodoanilines-derived carbamates and sodium sulfide
摘要:
A copper-catalyzed procedure was developed for assembling benzothiazolones from ethyl 2-iodophenylcarbamates and sodium sulfide. A number of functional groups, such as methoxy, acyl, amide, carboxylate, trifluoromethyl, fluoro, and chloro, were tolerated under these conditions, providing benzothiazolones in good yields.
