Stereoselective routes to N-Ph2PO-protected cis and trans meso-aziridino cyclohexene oxides have been developed. Enantioselective rearrangement of the cis epoxide with chiral bases gave the allylic alcohol in a maximum of 47% ee whilst that of the trans epoxide proceeded with enantioselectivity of up to 68% ee. Both these results demonstrate for the first time that chiral bases which smoothly rearrange
