Addition of dimethyloxosulfonium methylide to enantiomerically pure sulfinimines: Asymmetric synthesis of 2-substituted aziridines
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 auxillary in 3 was removed, without ring-opening, by treatment
