  日期：——

  An efficient, quantitative deracemization strategy for optically inactive allylic cycloalkanols has been achieved using the biphasic halogenative semi-pinacol reaction protocol. The resultant β-halo spiroketones, containing three contiguous stereogenic centers, were easily recovered with high diastereomeric and enantiomeric purities following conventional silica gel chromatography. The optically active products could be further manipulated chemically, affording synthetically interesting scaffolds with complete preservation of stereoisomeric integrity.

  利用双相卤代半频哪醇重排反应方案，已实现了一种高效、定量的消旋化策略，用于光学非活性的烯丙基环烷醇。生成的β-卤代螺酮，含有三个相邻的手性中心，通过常规硅胶柱层析可轻易回收，且具有高度的非对映异构和立体异构纯度。这些光学活性产物还可以进一步进行化学操作，获得合成上有趣的骨架，同时完全保留立体异构完整性。
