[reaction: see text] The synthesis of the C9-C26 portion of amphidinolide B1 is described. A Fleming allylation followed by elimination was employed for the construction of the C13-C15 diene portion. Sharpless asymmetric dihydroxylation was utilized for regioselective functionalization of a styrene-derived alkene, in the presence of the C13-C15 diene functionality. A highly diastereoselective aldol
[反应:见正文]描述了两性霉素B1的C9-C26部分的合成。弗莱明烯丙基化随后消除被用于构建C 13 -C 15二烯部分。在C13-C15二烯官能团存在的情况下,利用Sharpless不对称二羟基化技术对苯乙烯衍生的烯烃进行区域选择性官能化。开发了高度非对映选择性的醛醇缩合反应以建立C18立体化学。
