The reaction of aminothienopyridazines 8a,b, aminothienocoumarin 13 and aminothienonaphthopyran 14 with enaminones 9, 17 and 20a,b under microwave irradiation affords either a mixture of both condensations C-1 alkylation products 15 and 16 or amino moiety alkylation and diethylamine elimination or only one of these products depending on nature of substituents on the thiophene ring. On the other hand
aminothienopyridazines的反应8A,8B,aminothienocoumarin 13和aminothienonaphthopyran 14与烯胺酮9,17和20A,B在微波辐射下,得到两个都缩合的混合物C-1烷基化产物15和16只有一个或氨基部分烷基化和二乙胺去除或这些产物的种类取决于噻吩环上取代基的性质。另一方面,这些缩合的氨基噻吩与3-二甲基氨基丙烯醛的反应得到24和25。
