A stereoselective synthesis of the C1–C15 fragment of a G-actin binding natural macrodiolide, rhizopodin was achieved using, as key steps, highly stereoselective acetate aldol reactions to build the C1–C7 fragment, one pot oxazole synthesis and an asymmetric Keck allylation reaction to build the C8–C15 fragment and finally, a Stille reaction to couple both the fragments.
立体选择性合成G-肌动蛋白结合的天然大环糖苷,根瘤菌素的C1-C15片段,通过使用关键立体步骤,通过高度立体选择性的乙酸羟醛醛缩合反应构建C1-C7片段,一锅恶唑合成和不对称的Keck烯丙基化反应来实现来构建C8–C15片段,最后,进行斯蒂勒反应以将两个片段偶联在一起。
