the corresponding acid hydrazide 6. Finally, treatment of 1a,b,d with 2-amind-3-cyano-4,5,6,7-tetrahydrobenzo[b]thiophene yielded thieno[2,3-d]pyrimidines 10a-c bearing sulphonamido moieties. Structures of the new compounds were established by their elemental analyses and spectral data. Also, the most of these compounds were tested in vitro for their antimicrobial activity against some Gram positive and
摘要 对取代的氨磺酰基苯基异硫氰酸酯 1a-d 是使用报道的程序制备的。研究了 1a-d 对一些含氮亲核试剂的反应性。因此,1 与芳香胺和邻氨基苯甲酸的相互作用提供了 N1,N3-二取代硫脲 2a-c 和 3-[4-N-取代磺酰氨基]苯基-2-thioxo-4-(3H)-quinazolin-4-ones 4a -f,分别。在含有无水碳酸钾的丙酮中用氯乙酸乙酯将 4c 烷基化得到喹唑啉 5。使用乙醇水合肼对 5 进行肼解得到相应的酰肼 6。最后,用 2-氨基-3-氰基-4 处理 1a、b、d ,5,6,7-四氢苯并[b]噻吩生成含有磺酰氨基部分的噻吩并[2,3-d]嘧啶10a-c。新化合物的结构是通过元素分析和光谱数据确定的。还,
