Abstract

The present protocol demonstrates the synthesis of N-substituted saccharines via carbonylative cyclization of 2-iodosulfonamides using a Pd(OAc)2/Xantphos catalyst system and phenyl formate as a CO source. A variety of saccharin derivatives is synthesized under milder reaction conditions.
