The phorboxazoles A and B are a new class of biologically highly active macrolides. The enantiopure C28-C41 segment containing four stereogenic centers, an E-configurated trisubstituted double bond and the 2,4-difunctionalized oxazole moiety has been prepared in 16 steps in 10% overall yield. The synthesis represents advances in strategy and methodology.
phorboxazoles A 和 B 是一类具有高度生物活性的新型大环内酯类化合物。我们通过 16 个步骤制备了含有四个立体中心、一个 E 配置的三取代双键和 2,4-二官能化噁唑分子的对映体纯 C28-C41 段,总收率为 10%。该合成代表了策略和方法学的进步。
