The first stereoselective total synthesis of the naturally occurring anti‐emetic diarylheptanoid (3R,5R)‐1‐(4‐hydroxyphenyl)‐7‐phenylheptane‐3,5‐diol (1) was accomplished starting from 4‐hydroxybenzaldehyde and involving a Sharpless kinetic resolution and an asymmetric epoxidation as the key steps (Scheme 2). The enantiomer 1a of this compound was also simultaneously prepared.
天然存在的止吐二芳基庚烷(3 R,5 R)-1-(4-羟基苯基)-7-苯基庚烷-3,5-二醇(1)的第一个立体选择性全合成是从4-羟基苯甲醛开始的,涉及一个夏普勒斯动力学拆分和不对称环氧化的关键步骤(方案2)。还同时制备了该化合物的对映异构体1a。
