Abstract

The treatment of methyl erythro-2,3-dibromo-3-phenylpropionate (I), methyl cis- and trans-α-bromocinnamate (IIa, IIb) with benzylamine resulted in the formation of the same sole product cis-1-benzyl-2-methoxycarbonyl-3-phenylaziridine (III). A plausible stereochemical pathway was discussed. The compound III was converted to phenylalanine (V) by hydrogenation and threo-β-phenylserine (VI) by hydration reaction.
