Bicyclic lactams derived from pyroglutamic acid provide a useful scaffold for synthesis of conformationally restricted analogues of lysine, ornithine and glutamine, as well as an Ala-Ala dipeptide analogue. Amino alcohol and carboxylic acid derivatives are accessible from a common intermediate. In this strategy, the bicyclic lactam system not only controls, but also facilitates the determination of
衍生自焦谷氨酸的双环内酰胺为合成赖氨酸,鸟氨酸和谷氨酰胺的构象受限的类似物以及Ala-Ala二肽类似物提供了有用的支架。氨基醇和羧酸衍生物可从常见的中间体获得。在这种策略中,双环内酰胺系统不仅控制,而且还有助于确定合成中间体的立体化学。
