A practical procedure for the preparation of fused 1,4-dihydropyridines was developed through the domino four-component reactions of arylamines, acetylenedicarboxylate, aromatic aldehydes, and cyclic 1,3-diketones in acetic acid. Unusual fused 1,2-dihydropyridines can also be efficiently prepared by controlling the reaction conditions.
通过芳胺、乙炔二羧酸酯、芳香醛和环状 1,3-二酮在乙酸中的多米诺四组分反应,开发了制备稠合 1,4-二氢吡啶的实用程序。通过控制反应条件也可以有效地制备不寻常的稠合 1,2-二氢吡啶。
