The reaction of lauroyl isothiocyanate with ethyl 2-amino-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate gave ethyl 2-(3-dodecanoylthioureido)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate 3. Compound 3 could serve as a main building block in synthesis of the target heterocyclic systems like thieno[2,3-d]-pyrimidine, thieno[2′,3′:4,5]pyrimido[1,2-a][1,3,5]triazine, thieno[2,3-d]-1,3-thiazine and 1,2,4-triazole systems attached to the lauryl group. The structures of the synthesized target heterocyclic compounds were confirmed by microanalytical and spectral data. The antimicrobial activity of some of the synthesized compounds was tested.
异硫氰酸月桂酰基酯与 2-氨基-4,5,6,7-四氢苯并[b]噻吩-3-羧酸乙酯反应生成 2-(3-十二碳酰硫脲基)-4,5,6,7-四氢苯并[b]噻吩-3-羧酸乙酯 3。化合物 3 可作为合成噻吩并[2,3-d]-嘧啶、噻吩并[2′,3′:4,5]嘧啶并[1,2-a][1,3,5]三嗪、噻吩并[2,3-d]-1,3-噻嗪和连接月桂基的 1,2,4- 三唑等目标杂环系统的主要结构单元。微量分析和光谱数据证实了合成的目标杂环化合物的结构。对一些合成化合物的抗菌活性进行了测试。
