Substituted 5-aminopyrido[3′,2′:4,5]thieno[3,2-c]isoquinolines were synthesized by condensation of substituted 3-cyanopyridine-2(1H)-thiones with 2-(chloromethyl)benzamide and subsequent treatment of the condensation products with potassium tert-butoxide. Oxidation of the condensation products to sulfoxides and sulfones followed by treatment of these compounds with potassium tert-butoxide gives substituted
取代的 5-氨基吡啶并[3',2':4,5]噻吩并[3,2-c]异喹啉通过取代的3-氰基吡啶-2(1H)-硫酮与2-(氯甲基)苯甲酰胺缩合和后续处理合成与叔丁醇钾的缩合产物。将缩合产物氧化成亚砜和砜,然后用叔丁醇钾处理这些化合物,得到取代的 5-氨基吡啶并[3',2':4,5]噻吩并[3,2-c]异喹啉11-氧化物和取代的5-氨基吡啶并[3',2':4,5]噻吩并[3,2-c]异喹啉11,11-二氧化物产率良好。
