A process for the preparation of optically pure .alpha.-amino acids comprising the nucleophilic ring-opening of 3-amino-2-oxetanone salts. N-Protected serine .beta.-lactones are deprotected to form heretofore unknown 3-amino-2-oxetanone and its corresponding salts. In turn these previously unknown 3-amino-2-oxetanone salts may be used in the synthesis of other novel or rare stereochemically-pure free amino acids.
