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