摘要
A highly stereoselective synthesis of tetrasubstituted monofluoroalkenes with aldehydes and fluorobis(phenyl- sulfonyl)methane (FBSM) in one pot has been developed. The reaction was amenable topara- and meta-substituted aryl aldehydes, 2-naphthaldehyde, and cinnamaldehyde, giving phenylsulfonyl-substituted monofluoroalkenes in 40%--86% yields with 98/2- 99/1 Z/E ratios. The presence of the sulfonyl group enables the further transformation of the products into more useful monofluoroalkenes.
