straightforward, five-step procedure for the synthesis of enantiomerically pure 2,3-disubstituted trans-aziridines has been developed starting from commercially available aldehydes. Hydroxynitrile lyase-mediated cyanohydrin formation provided cyanohydrins in excellent enantioselectivities and good yields. Subsequent formation of diastereomerically pure anti-amino alcoholsvia a one-pot Grignard addition−reduction
