Opticallyactive sulfinylaziridines having a 4-methoxyphenyl group on their nitrogen atom were synthesized fromopticallyactive 1-chloroalkyl p-tolyl sulfoxide and an imine derivedfrom benzaldehyde and p-anisidine stereoselectively in good overall yields. The sulfinylaziridines were treated with ethylmagnesium bromide or tert-butyllithium to afford aziridinylmagnesiums or aziridinyllithiums, respectively
