专利号:US-5200526-A 优先权日:1987-04-27 标题:Syntheses of optically pure α-amino acids from 3-amino-2-oxetanone salts 发明人:ARNOLD LEE D; VEDERAS JOHN C 权利人:UNIV ALBERTA 摘要:A process for the preparation of optically pure α-amino acids comprising the nucleophilic ring-opening of 3-amino-2-oxetanone salts. N-Protected serine β-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.
