Highly stereoselective aziridination of imines with (S)-dimethylsulfonium-(p-tolylsulfinyl)methylide
摘要:
Addition of (S)-dimethylsulfonium-(p-tolylsulfinyl)methylide to N-tosyl imines afforded the corresponding sulfinyl aziridines with full enantio- and diastereoselectivity. The chiral sulfinyl substituent was removed without ring opening leading to enantiopure 2-substituted aziridines. (C) 2007 Elsevier Ltd. All rights reserved.

A chiral cyclopentadienyl-rhodium(III) catalyzedhighly enantioselective aziridination of challenging unactivatedterminalalkenes and N-pivalolyloxy sulfonamides has been developed. This catalytic system demonstrated outstanding catalytic activity and broad functional group tolerance, yielding synthetically important and highly valuable chiral aziridines with good to excellent yields and enantioselectivities
