paper we report the development of a highly enantioselective method for the synthesis of aroylalanines. The approach described employs a protected 2-amino-4-bromopent-4-enoic acid, generated via the asymmetric phase-transfer catalyzed alkylation of a glycine imine, as a key intermediate. Suzuki coupling with an aryl boronic acid followed by ozonolysis of the resulting styrene provides efficient access
在本文中,我们报告了合成芳基丙氨酸的高对映选择性方法的发展。所描述的方法使用通过甘氨酸亚胺的不对称相转移催化的烷基化反应生成的受保护的2-氨基-4-溴戊-4-烯酸作为关键中间体。Suzuki与芳基硼酸偶联,然后进行臭氧氧化生成的苯乙烯,可以有效地获得芳酰丙氨酸衍生物。该方法的实用性通过1-犬尿氨酸与犬尿氨酸途径的几种芳基丙氨酸抑制剂的合成来说明。
