A series of new thiophene compounds 6a-6l was synthesized from the reactions of in situ generated cross-conjugated enaminothiones 2 and α-bromoketones/ethyl bromoacetate. Moreover, the synthesis of 1,3-thiazine 12 and functionalized thiopyran 18 heterocycles from the cycloaddition reactions of N,N’-bis[(dimethylamino)methylene]thiourea 9, is also described. Additionally, the binding conformations of
由原位产生的交叉共轭烯氨基硫酮2和α-溴酮/溴乙酸乙酯反应合成了一系列新的噻吩化合物6a-6l。此外,还描述了从 N,N'-双 [(二甲氨基) 亚甲基] 硫脲 9 的环加成反应合成 1,3-噻嗪 12 和官能化的噻喃 18 杂环。此外,这些化合物 6a-6l 和一些抗炎药 (NSAID) 的结合构象是通过它们在 Cyclooxygenase-2 (COX-2) 酶的活性位点的对接来确定的。
