Asymmetricintramoleculardirecthydroarylation of α‐ketoamides gives various types of optically active 3‐substituted 3‐hydroxy‐2‐oxindoles in high yields with complete regioselectivity and high enantioselectivities (84–98 % ee). This is realized by the use of the cationic iridium complex [Ir(cod)2](BArF4) and the chiral O‐linked bidentate phosphoramidite (R,R)‐Me‐BIPAM.
α-酮酰胺的不对称分子内直接氢芳基化反应可高产率获得各种类型的旋光3-取代3-羟基2-羟吲哚,具有完全的区域选择性和高对映选择性(84–98%ee)。这是通过使用阳离子铱络合物[Ir(cod)2 ](BAr F 4)和手性O联双齿亚磷酰胺(R,R)-Me-BIPAM来实现的。
