The first total synthesis of rhuscholide A, a benzofuran lactone possessing anti-HIV-1 activity, had been accomplished in 14 linear steps with 10.6% overall yield. In this synthesis, base-mediated phenol ortho-alkylation and piperidine promoted aldol condensation were exploited as key steps. The synthesis was flexible and allowed for the convenient preparation of two analogous natural products glabralide
具有14个线性步骤,以14.6%的总收率完成了具有抗HIV-1活性的苯并呋喃内酯Rhuscholide A的第一个全合成。在该合成中,将碱介导的苯酚正烷基化和哌啶促进的醇醛缩合用作关键步骤。该合成是灵活的,并且允许方便地制备两种类似的天然产物glabralide B和denudalide。
