functionalized 1,3‐diol derivatives is reported. Employing a copper‐catalyzed oxy‐alkenylation strategy, a range of readily available, substituted homoallylic alcohol derivatives and alkenyl(aryl) iodonium salts combine to form syn‐1,3‐carbonates in excellent yield and with high selectivity. Furthermore, the products formed are amenable to an iterative reaction sequence, thus affording highly complex polyketide‐like
报道了一种新型的合成多种功能化的1,3-二醇衍生物的方法。采用铜催化的氧-烯基化策略,一系列易于获得的取代的均烯丙基醇衍生物和烯基(芳基)碘鎓盐以优异的收率和高选择性结合形成顺式1,3-碳酸酯。此外,所形成的产物适合重复的反应序列,从而提供了高度复杂的聚酮化合物样片段。
