Rhodium(III)-catalyzed coupling of N-sulfonyl 2-aminobenzaldehydes with oxygenated allylic olefins through C–H activation

Author affiliations

Abstract

Rh(III)-catalyzed coupling of N-sulfonyl 2-aminobenzaldehydes with oxygenated allylic olefins via C–H bond activation is described. Diarylketones were obtained through coupling of N-sulfonyl 2-aminobenzaldehydes with 7-oxabenzonorbornadienes. On the other hand, the coupling with allyl carbonate yielded a six-membered sulfonyl lactam via a sequence of allylation–isomerization–Michael cyclization.
