The reactivity of the Z-protected aziridine derivedfrom aspartic acid has been studied with various N- and O-nucleophiles. The optimized reaction conditions allow quick and easy access to 1, 2-diamines or amino alcohols. In the case of opening with N-nucleophiles, very good regioselectivity was observed. Use of an α-amino ester as the nucleophile yielded a methyleneamino pseudodipeptide.
