A method for chemoselective reduction of 2-pyridyl ketones and related N-heteroaryl compounds catalyzed by cobalt stearate using DMF as a hydride source is developed. The ketone substrate is activated by chelation with cobalt, which makes the present method highly chemoselective. A possible reaction mechanism is proposed on the basis of control experiments.

以 N,N-二甲基甲酰胺为氢化物源的钴催化 N-杂芳基酮的化学选择性还原

开发了一种在硬脂酸钴催化下，使用 DMF 作为氢化物源化学选择性还原 2-吡啶基酮和相关N-杂芳基化合物的方法。酮底物通过与钴螯合而被激活，这使得本方法具有高度化学选择性。在对照实验的基础上提出了一种可能的反应机理。
