ABSTRACT An efficient, catalyst-free, microwave-assisted approach has been developed for the synthesis of 2-aryl/alkyl-3-(1H-benzo[d]imidazol-2-yl)-2,3-dihydroquinazolin-4(1H)-one derivatives by condensing 2-aminobenzamides with various aliphatic, aromatic, and heterocyclic aldehydes. This catalyst-free approach exhibited good functional group compatibility and produced the desired products in good
摘要 一种高效、无催化剂、微波辅助的方法已被开发用于合成 2-芳基/烷基-3-(1H-苯并[d]咪唑-2-基)-2,3-二氢喹唑啉-4(1H )-一种通过将 2-氨基苯甲酰胺与各种脂肪族、芳香族和杂环醛缩合而成的衍生物。这种无催化剂的方法表现出良好的官能团兼容性,并在短短 10-20 分钟内以良好到极好的收率生产了所需的产品。这种方法可以看作是用于合成此类化合物的金属催化方案的更好替代方案。X射线分析也证实了所需化合物的形成。图形概要
