An unprecedented NH4I-promoted N-formylation and N-acetylization of various amines with dimethylformamide (DMF) and dimethylacetamide (DMA) has been developed. This protocol shows broad substrate scope for aromatic, aliphatic, and heterocyclic amines, which provides a metal-free strategy for N-acylation featuring mild reaction conditions, as well as inexpensive and readily available starting materials
已经开发出前所未有的NH 4 I促进的各种胺与二甲基甲酰胺(DMF)和二甲基乙酰胺(DMA)的N-甲酰化和N-乙酰化。该方案显示了芳香族,脂肪族和杂环胺的广泛底物范围,从而为温和的反应条件以及廉价且易于获得的起始原料提供了无金属的N酰化策略。
