Addition of dimethyloxosulfonium methylide to enantiomerically pure sulfinimines: Asymmetric synthesis of 2-substituted aziridines
摘要:
Diastereoselective addition of dimethyloxosulfonium methylide to chiral nonracemic pure sulfinimines 1 affords N-sulfinyl aziridines 3 in 58-70% de which are readily separated. The N-sulfinyl auxiliary in 3 was removed, without ring-opening, by treatment with MeLi.
