modification of N-acyl-protected phenylglycine sometimes causes racemization due to the fact that the phenyl ring is directly connected to the α-position of the α-amino acid skeleton. In this report, synthesis and the property of N-trifluoroacetylphenylglycine hydroxysuccinimide ester was archived.
苯甘氨酸是非蛋白质的α-氨基酸,其部分结构存在于一些生物活性化合物中。N-酰基保护的苯甘氨酸的 C 末端修饰有时会导致外消旋化,因为苯环直接连接到 α-氨基酸骨架的 α 位。本报告对N-三氟乙酰苯基甘氨酸羟基琥珀酰亚胺酯的合成及其性质进行了归档。

corresponding amino acids. The conversion of the dipeptides to the corresponding dipeptide esters, followed by their subsequent spontaneous cyclization afforded the corresponding stereoisomerically purediketopiperazines.
