efficient method to build enantioenriched organoborones with two consecutive stereogenic centers. It is worth noting that this protocol represents a new organocatalytic manner to generate chiral β-C–B bonds. Moreover, it also greatly enriches the structural diversity of the chiral organoboron compounds.
我们报道了卡宾催化的活化酯和β-
硼酸烯酮的[4 + 2]环化,提供了一种构建具有两个连续立体中心的对映体富集的有机
硼酮的有效方法。值得注意的是,该方案代表了一种生成手性 β-C-B 键的新有机催化方式。此外,它也极大地丰富了手性有机
硼化合物的结构多样性。
