A copper-catalyzed condensation reaction of oxime acetates and α,β-unsaturated ketimines to give pyridine derivatives is reported. The reaction features mild conditions, high functional-group compatibility, and high regioselectivity with respect to unsymmetrical oxime acetates, thus allowing the preparation of a wide range of polysubstituted pyridines, many of which are not readily accessible by conventional
据报道,乙酸肟肟和α,β-不饱和酮亚胺在铜催化下缩合反应生成吡啶衍生物。该反应具有温和的条件,相对于不对称肟肟酸酯的高官能团相容性和高的区域选择性,因此可以制备多种多取代的吡啶,其中许多不易通过常规缩合方法获得。
