Abstract
Rh(III) catalyzed oxidative synthesis of 1,2-benzothiazine derivatives using sulfoximine as a directing group under C-H activation strategy is reported. In this study, we utilized arylalkynyl silanes as an alternate for terminal alkynes to obtain the 1,2-benzothiazine derivatives via desilylation pathway. The developed methodology shows a good range of functional group tolerance and furnished the products in moderate yields.
