4-oxopipecolic esters were converted into cyclic analogues of bishomoaspartic acid and homoglutamic acid by Homer-Wadsworth-Emmons olefination and hydrogenation. Condensation of the side chain carboxylic group with anomeric glucosylamine and suitable protection of the α-amino acid moiety afforded the corresponding N-glucosyl asparagine or glutamine mimetics as useful building blocks in glycopeptidomimetic
Enantiopure 叔丁基 4-oxopipecolic 酯通过荷马-沃兹沃思-埃蒙斯烯化和氢化转化为双天冬氨酸和高谷氨酸的环状类似物。侧链羧基与异头葡糖胺的缩合和 α-氨基酸部分的适当保护提供了相应的 N-葡糖基天冬酰胺或谷氨酰胺模拟物,作为糖肽模拟物合成中有用的结构单元。
