The reaction of trimethylsilyldiazomethane with N-sulfonyl (Ts and SES) imines provides aziridines in good yields and high cis stereoselectivities. The silyl group can be substituted by treatment with a fluoride source and electrophiles again with high selectivity. In addition, complete regioselectivity is observed in ring opening reactions of these aziridines with nucleophiles.
