An efficient and stereodefined strategy is described for the asymmetric synthesis of a new styryllactone from the stem bark of Goniothalamus cardiopetalus, cardiobutanolide. The synthetic process is based on requisite manipulation of the functionalized bicyclic lactol–lactone intermediate incorporating the glucuronolactone-derived skeleton in a complete stereoselective manner.
描述了一种有效且立体明确的策略,该方法用于从心叶禾本科(Goniothalamus cardiopetalus),心脏丁醇内酯的茎皮中不对称合成新的苯乙烯基内酯。合成过程基于对功能化的双环乳酸-内酯中间体的必要操作,该中间体以完全立体选择性的方式结合了葡萄糖醛酸内酯衍生的骨架。
