The three naturally occurring, bioactive spiroacetals aculeatins A, B, and D, as well as the non-natural 6-epi-aculeatin D have been synthesized for the first time in enantiopure form using an asymmetric allylation as the only chirality source. A further key step was a stereoselective aldol reaction with remote induction. The absolute configurations of the natural products have been established and
使用不对称烯丙基化作为唯一手性来源,首次以对映纯形式合成了三种天然存在的,具有生物活性的螺缩醛aculeatins A,B和D以及非天然的6- epi -aculeatinD 。另一个关键步骤是具有远程感应的立体选择性醛醇缩合反应。已经确定了天然产物的绝对构型,并且纠正了错误的结构分配。
