enantioselectivities up to >99:1 er under the optimized conditions. The utility of the current method was further established by rapid conversion of an adduct to a chiral benzo[f][1,4]oxazepine. A model for the stereochemistry of the asymmetric aminoboration process, which agrees with the experimental outcomes, was generated by computational analysis of the systems.
报道了具有piv ZPhos作为配体的Cu催化的E-乙烯基芳烃的对映选择性氨基硼化。在优化的条件下,制备的对映体富集的氨基硼酸盐具有高达> 99:1的极佳区域选择性和对映体选择性。通过将加合物快速转化为手性苯并[ f ] [1,4]奥氮平,进一步建立了当前方法的实用性。通过系统的计算分析,生成了与实验结果相符的不对称氨基硼酸酯化过程立体化学模型。
