strategies have been considered to achieve the first total synthesis of nhatrangins A and B. The first approach based on a cross metathesis (CM) reaction was unsuccessful. The second, which combined a highly stereoselective alkylation, a diastereoselective aldolization, and finally an esterification, furnished an advanced aldehyde intermediate bearing the three contiguous stereogenic centres and the expected
已经考虑了两种不同的策略来实现首次全合成 nhatrangins A 和 B。基于交叉复分解 (CM) 反应的第一种方法是不成功的。第二个结合了高度立体选择性烷基化、非对映选择性醛醇化和最后的酯化,提供了带有三个连续立体中心和预期侧链的高级醛中间体。
