The acid-catalyzed reaction of 3-aminothiophene with one-half equivalent of aliphatic or aromatic aldehyde leads to the formation of dithieno[3,2-b:2′,3′-e]pyridines after transamination and dehydrogenation. The corresponding dihydropyridines were also prepared from bis(3-thienyl)amine.
3-氨基噻吩与二分之一当量的脂族或芳族醛的酸催化反应导致氨基转移和脱氢后形成二噻吩并[3,2-b:2',3'-e]吡啶。相应的二氢吡啶也由双(3-噻吩基)胺制备。
