A practical zinc acetate dihydrate‐catalyzed reductive amination of various carbonyl compounds with N,N‐dimethylformamide (DMF) as dimethylamino (Me2N) source, reductant and solvent has been developed. This reaction shows broad substrate scope, good functional group tolerance, avoids the need for a pressure‐proof reactor and column chromatographic isolation operations and gives up to 98% yield, to
已经开发了一种实用的乙酸锌二水合物催化的羰基化合物以N,N-二甲基甲酰胺(DMF)作为二甲基氨基(Me 2 N)来源,还原剂和溶剂的还原胺化方法。该反应显示出广泛的底物范围,良好的官能团耐受性,无需耐压反应器和色谱柱色谱分离操作,且收率高达98%,使其成为制备N,N-二甲基叔胺的有吸引力的方法。
