Catalytic kinetic resolution of racemic organic compounds is a reliable method to enantioselectively prepare important chiral molecules. Substrates for the kinetic resolution, however, generally required significantly different substituents at a chiral center. Catalytic kinetic resolution of racemic molecules possessing two similar substituents at a chiral center has remained a formidable challenge
外消旋有机化合物的催化动力学拆分是对映选择性制备重要手性分子的可靠方法。然而,用于动力学拆分的底物通常需要在手性中心有明显不同的取代基。在手性中心具有两个相似取代基的外消旋分子的催化动力学拆分仍然是一项艰巨的挑战。在这种情况下,我们开始对在手性中心带有烯丙基和炔丙基的外消旋化合物的催化动力学拆分感兴趣,它们是相似但有用的取代基。在此,我们报告了通过手性双功能硫化物催化的溴内酯化对带有全碳季立构中心的 α-烯丙基-α-炔丙基羧酸进行动力学拆分。
