The ring expansion of 3-unsubstituted (R)-aziridine-2-imide- containing dipeptide under acidic conditions gives rise to oxazoline-5-imide regio and stereoselectively, which can be hydrolysed to the dipeptide containing D-isoserine. On the other hand, the ring opening of 3-unsubstituted (R)-aziridine-2-ester dipeptide, easily obtained from the same (R)-aziridine, gives the regioisomeric dipeptide containing D-serine.
