[structure: see text] A convergent and stereoselective assembly of the C1-C14 subunit of marine natural product (+)-discodermolide has been completed. The approach employs chiral allylsilane bond construction methodology to establish four of the eight stereogenic centers. Key fragment coupling is achieved via an efficient stereoselective acetate aldol reaction between C1-C6 and C7-C14 subunits.
[结构:见正文]海洋天然产物(+)-discodermolide的C1-C14亚基的会聚和立体选择性组装已完成。该方法采用手性烯丙基硅烷键构建方法来建立八个立体异构中心中的四个。关键片段的偶联是通过C1-C6和C7-C14亚基之间有效的立体选择性乙酸酯羟醛反应实现的。
