convergent synthesis of the annonaceous acetogenin, 10-hydroxytrilobacin ( 4a), was accomplished by using the [3 + 2]-annulation reaction of tetrahydrofuranyl carboxaldehyde 2a and allylsilane 3. The stereodivergency of the [3 + 2]-annulation reaction made it possible to achieve modular, highly stereoselective syntheses of three 10-hydroxytrilobacin diastereomers from the same precursors by using simple
通过使用四氢呋喃基甲醛2a和烯丙基硅烷3的[3 + 2]环合反应,可以完成壬基产乙酸原素10-羟基三叶草素(4a)的聚合反应。通过简单地改变反应条件,就可以从相同的前体中获得模块化的,高度立体选择性的三种10-羟基三叶球蛋白非对映异构体的合成方法。
