The stereoselective synthesis of the fully functionalized northern hemisphere of the marine natural product amphidinolide H2 is described. A vinylogous Mukaiyama aldol reaction and enzymatic desymmetrization of a meso compound are the key steps in the fragment synthesis. A stereoselective acetate aldol coupling and a 1,3-anti-reduction of the resulting β-hydroxy ketone complete the synthesis of the C14-C26 fragment.
本研究描述了海洋天然产物蚜虫内酯 H2 的全官能化北半球的立体选择性合成。片段合成的关键步骤是乙烯基Mukaiyama醛醇反应和中间化合物的酶解不对称反应。立体选择性醋酸酯醛醇偶联反应和由此产生的δ-羟基酮的 1,3-反还原完成了 C14-C26 片段的合成。
