against Plasmodium falciparum K1. Structurally, it features a decanolide with a trans-double bond attached to two chiral hydroxy groups, making the total synthesis of the exclusive isomer of 1 more difficult. Herein, we report the successful synthesis of 1 by employing a MacMillan α-hydroxylation to generate three chiral centers in both the key fragments, starting from 1,6-hexanediol and 1,4-butanediol
Nonnolide(1)首先从昆虫病原菌虫草虫草BCC2816中分离出来,对恶性疟原虫K1表现出良好的抗疟活性。在结构上,它的特征是癸醇化物具有连接到两个手性羟基上的反式双键,这使得1的排他异构体的全合成更加困难。本文中,我们报道了通过MacMillanα-羟基化反应成功合成1的过程,在两个关键片段中生成了三个手性中心,从1,6-己二醇和1,4-丁二醇开始,然后进行Steglich酯化化合物2和3。独家E异构体是通过单-PMB-保护的二烯19的闭环复分解获得的。脱保护得到所需的天然产物1。
