Nickel catalysts of chiral pyrox ligands promoted enantioselective reductive arylation and heteroarylation of aldimines, using directly (hetero)aryl halides and sulfonates. The catalytic arylation can also be conducted with crude aldimines generated from condensation of aldehydes and azaaryl amines. Mechanistically, density functional theory (DFT) calculations and experiments pointed to an elementary
手性 pyrox 配体的镍催化剂促进醛亚胺的对映选择性还原芳基化和杂芳基化,直接使用(杂)芳基卤化物和磺酸盐。催化芳基化也可以用醛和氮杂芳基胺缩合产生的粗醛亚胺进行。从机理上讲,密度泛函理论 (DFT) 计算和实验指出了芳基镍 (I) 配合物与N-氮杂芳基醛亚胺1,4-加成的基本步骤。
