5-dichlorothiophene-3-carbonyl chloride, and model heterocyclic amines produced the respective 2,5-dichloro- N -(substituted aminocarbonothioyl)thiophene-3-carboxamides. Upon heating, the deprotonated form of the latter underwent intramolecular cyclization to deliver the corresponding 2-(substituted amino)-4 H -thieno[3,2- e ]-1,3-thiazin-4-ones. The structures of these new bicyclic derivatives and their acyclic
经由 2,5-二氯噻吩-3-羰基氯可及的2,5-二氯噻吩-3-羰基异硫氰酸酯与模型杂环胺的相互作用 产生了各自的2,5-二氯 -N- (取代的氨基碳硫代羰基)噻吩-3-羧酰胺。 。加热后,后者的去质子化形式进行分子内环化以递送相应的2-(取代的氨基)-4 H- 噻吩并[3,2 - e ] -1,3-噻嗪-4-酮。这些新的双环衍生物及其无环前体的结构基于微观分析和光谱(IR,MS和NMR)数据。
