Readily available N1,N3-diacyl-3,4-dihydropyrimidin-2(1H)-ones efficiently acylate ammonia, primary and secondary amines to furnish primary, secondary and tertiary amides in good to excellent yields. The wide applicability of the procedure is demonstrated by running the reactions in a neutral medium, easy isolation of products, recycling of the innocuous by-product and chemoselectivity of the transformation
易于获得的N 1,N 3-二酰基3,4-二氢嘧啶-2(1 H)-一有效地酰化氨,伯胺和仲胺,从而以良好或优异的收率提供伯,仲和叔酰胺。通过在中性介质中进行反应,易于分离产物,回收无害副产物和进行转化的化学选择性,证明了该方法的广泛适用性。
