A synthesis of two structurally related macrodiolides representing the aglycone of natural products elaiophylin and halichoblelide is described. The key transformation for both is a Ti(II)-mediated (silyloxy)enyne cyclization, generating a new methyl stereocenter and providing a diene that can be selectively cross metathesized with crotonic acid.
描述了两种代表天然产物elaiophylin和halichoblelide的糖苷配基的结构相关的大环糊精的合成。两者的关键转化是Ti(II)介导的(甲硅烷氧基)炔炔环化,生成新的甲基立体中心,并提供可以与巴豆酸选择性地交叉复分解的二烯。
