An efficient route to the neocarzinostatin chromophore aglycon has been developed. The present strategy involves a stereoselective intramolecular acetylide−aldehyde cyclization to form the C5−C6 bond, followed by efficient installation of α-epoxide, naphthoate, and carbonate functionalities. The C8−C9-olefin was introduced by using the Martin sulfurane dehydration reaction to furnish the highly reactive
已开发出一种新的抗人他汀类生色团糖苷配基的有效途径。本策略涉及立体选择性分子内乙醛-醛环化形成C5-C6键,然后有效安装α-环氧化物,萘甲酸和碳酸盐官能团。通过使用马丁硫烷脱水反应引入C8-C9烯烃,以提供高反应活性的糖苷配基。
