Two alternative and straightforward routes were developed for the construction of (R)-goniothalamin, a natural anticancer agent. The first method starts with (R)-glycidol involving stereoselective (partial) reduction of alkyne and sulfoxide Julia-Lythgoe olefination as key steps. Second method deals with the synthesis of (R)goniothalamin from 2,3-O-isopropylidene-D-glyceraldehyde with partial reduction
为构建 (R)-goniothalamin(一种天然抗癌剂)开发了两种替代且直接的途径。第一种方法从 (R)-缩水甘油开始,包括炔烃和亚砜 Julia-Lythgoe 烯化的立体选择性(部分)还原作为关键步骤。第二种方法涉及从 2,3-O-异亚丙基-D-甘油醛合成 (R)goniothalamin,其中部分还原腈和 Still-Gennari 立体选择性烯化作为关键步骤。这两种标准有机反应顺序简单的方法可用于有机化学二、三年级课程。
