Organocatalytic 1,5-trifluoromethylthio-sulfonylation of vinylcyclopropane mediated by visible light in the water phase

Abstract

1,2-Difunctionalization has developed into a robust tool for the preparation of complex organic molecules, and remote difunctionalization has also aroused widespread interest to achieve pluripotency of difunctionalization. Herein, we report a metal-free organocatalytic system mediated by visible light to realize the remote 1,5-trifluoromethylthio-sulfonylation of vinylcyclopropane with ArSO₂SCF₃ reagents in the water phase. This reaction exhibits broad functional group compatibility, moderate to good yields, and high regioselectivities and stereoselectivities.
