Trimethylsilyldiazomethane smoothly reacts with N-sulfonylaldimines to give 2-substituted N-sulfonyl-3-trimethylsilylaziridines in good yields with high cis selectivity.

[GRAPHICS]Trimethylsilyldiazomethane has been found to add directly to N-sulfonyl (Ts and SES) imines to afford 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. Complete regioselectivity is observed in ring opening of these aziridines with nucleophiles.
