Rhodium(iii)-catalyzed oxidative olefination of N-allyl sulfonamides

Abstract

Rhodium(III)-catalyzed oxidative couplings between N-sulfonyl allylamines and activated olefins have been achieved. Only olefination occurred for acrylates, and the butadiene product can be further cyclized under palladium-catalyzed aerobic conditions. The coupling with N,N-dimethylacrylamide followed a cyclization pathway.
