The first total synthesis of Monocillin I related macrolides has been achieved by a convergent and stereospecific route involving the palladium - catalyzed coupling of a functionnalized chiral vinylstannane with the appropriate dimethoxy bromomethyl isocoumarin. Cleavage conditions of the isocoumarin ring were then found for the preparation of a precursor hydroxy acid. The 14-membered macrolide was
Monocillin I相关大环内酯类化合物的第一个全合成方法是通过聚合和立体定向途径实现,该途径涉及功能化手性乙烯基锡烷与适当的二甲氧基溴甲基异香豆素的钯催化偶联。然后发现异香豆素环的裂解条件以制备前体羟基酸。在Mitsunobu反应条件下获得14元大环内酯,并从该大环前体立体定向生成所需的Monocillin I天然共轭二烯酮环氧体系。
