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 (71%; ≥ 95% optical yield over 4 steps). Key features include the use of acid-labile protecting groups for the amino (Bod) and carboxyl (diphenylmethyl ester) groups, and the use of the phenylselenolate equivalent derived from sodium borohydride and diphenyl diselenide for L-homoserine lactone cleavage.
描述了从 L-高丝氨酸内酯合成 L-α-乙烯基甘氨酸的程序。所开发的路线方便(仅需要一个色谱步骤)且高效(71%;4 个步骤光学产率≥ 95%)。主要特点包括对氨基 (Bod) 和羧基(二苯基甲酯)基团使用酸不稳定保护基团,以及使用源自硼氢化钠和二苯基二硒化物的苯基硒酸盐等价物进行 L-高丝氨酸内酯裂解。
