A procedure for the synthesis of L-α-vinylglycine from L-homoserine lactone is described. The route developed is convenient (only one chromatography step is required) and efficient (72% yield; ≥95% optical yield over 4 steps). Key features include the use of acid-labile protecting groups for the amino (Boc) and carboxyl (diphenylmethyl ester) groups, and the use of the phenylselenolate equivalent derived from sodium borohydride and diphenyl diselenide for L-homoserine lactone cleavage.
本文描述了一种从L-高丝氨酸内酯合成L-α-乙烯基甘氨酸的方法。所开发的路线简便(仅需一步色谱步骤)且高效(产率72%;4步反应的光学产率≥95%)。关键特征包括对氨基(Boc)和羧基(二苯甲酯)使用对酸不稳定的保护基团,以及使用由硼氢化钠和二苯二硒化物衍生的苯硒醇盐等价物来裂解L-高丝氨酸内酯。
