alternative synthetic routes have been developed for the preparation of variolin B and deoxyvariolin B. The strategy is based on the preparation of the core tricyclic ring common to all variolins, pyrido[3',2':4,5]pyrrolo[1,2-c]pyrimidine, followed by a palladium-catalyzed cross-coupling reaction to give the tetracyclic system.
已开发出两种可供选择的合成途径来制备水痘蛋白B和脱氧水痘蛋白B。该策略基于制备所有水痘蛋白共有的核心三环,即pyrido [3',2':4,5] pyrrolo [1, 2-c]嘧啶,然后进行钯催化的交叉偶联反应,得到四环系统。
