The first examples of asymmetricoxidativecoupling of simple phenols and 2-hydroxycarbazoles are outlined. Generation of a more vanadium catalyst by ligand design and by addition of an exogenous Brønsted or Lewis acid was found to be key to coupling the more oxidatively resistant phenols. The resultant vanadium complex is both more Lewis acidic and more strongly oxidizing. Good to excellent levels
概述了简单酚和 2-羟基咔唑的不对称氧化偶联的第一个例子。通过配体设计和添加外源布朗斯特酸或路易斯酸生成更多钒的催化剂被发现是偶联更具抗氧化性的酚的关键。所得的钒络合物具有更强的路易斯酸性和更强的氧化性。可以获得良好至优异的对映选择性,并且简单的研磨即可轻松提供≥95% ee 的产品。
