The first stereoselective synthesis of polyketide natural product (3R,6S)-6-hydroxylasiodiplodin (1) has been described starting from commonly available starting materials d-mannitol and 2,4,6-trihydroxybenzoic acid. The key reactions involved are Keck asymmetric allylation, Stille coupling, De Brabander’s esterification, and ring-closing metathesis (RCM) reaction. The total synthesis was achieved
已经描述了从通常可得到的起始原料d-甘露糖醇和2,4,6-三羟基苯甲酸开始的聚酮化合物天然产物(3 R,6 S)-6-羟基二硫双胍(1)的第一次立体选择性合成。涉及的关键反应是Keck不对称烯丙基化,Stille偶联,De Brabander的酯化反应和闭环复分解(RCM)反应。以19.3%的总收率实现了总合成,这使得该路线很重要。
