A new, catalytic, and general methodology for the synthesis of biaryls and heterobiaryls by the cross coupling of anthranilamide derivatives (o-NMe2 benzamides) with aryl boroneopentylates is described. The reaction proceeds under catalytic RuH2(CO)(PPh3)3 conditions driven by the activation of the unreactive C–N bond by amide directing group (DG)-Ru catalyst chelation. High regioselectivity, orthogonality

甲酸酯的交叉偶联来合成联芳基和杂联二芳基的新的,催化的和通用的方法。反应在催化的RuH 2(CO)(PPh 3)3条件下进行,该条件由酰胺直接基团(DG)-Ru催化剂螯合活化未反应的C-N键所驱动。这些区域反应的特征是区域选择性高,与Suzuki-Miyaura反应具有正交性,操作简便且易于放大,这些特征可能有助于工业应用。
