stereoselective total synthesis of the reported structure of goniotrionin (4) has been accomplished. The key steps involved the opening of a chiral epoxide, a highlydiastereoselectiveMukaiyama aerobic oxidative cyclization, a selective 1,2-syn Mukaiyamaaldolreaction, and a Noyori reduction.
已经完成了所报道的促性腺激素(4)结构的立体选择性全合成。关键步骤包括打开手性环氧化物,高度非对映选择性的Mukaiyama有氧氧化环化,选择性的1,2- Syn Mukaiyama羟醛反应和Noyori还原。
