on Shibasaki’s N-linked BINOL was synthesized. This ligand appears to be highly effective for rhodium-catalyzed asymmetric conjugated addition of arylboronic acids to α,β-unsaturated enones. The reaction of ortho-substituted arylboronic acid with acyclic and cyclic enones provides the corresponding products in good yields and enantioselectivities.
合成了一种基于 Shibasaki 的 N-linked BINOL 的新型双齿亚磷酰胺 (N-Me-BIPAM)。该配体对于铑催化的芳基硼酸与α,β-不饱和烯酮的不对称共轭加成非常有效。邻位取代的芳基硼酸与无环和环状烯酮的反应以良好的产率和对映选择性提供相应的产物。
