chloroacetonitrile. These compounds were conveniently converted into novel pyrido[4′,5′:4,5]thieno[3,2-d]pyrimidines. Also, 2,3-dihydro-1,3,4-thiadiazole was synthesized from hydrazonoyl halides and 2-benzofuran-2-yl-3-(phenylamino)-3-thioxopropanenitrile. The structures of the products have been elucidated by elemental analyses, spectral data studies, and alternative syntheses whenever possible. The
噻吩并[2,3-b]吡啶由6-苯并呋喃-2-基-4-苯基-2-硫烷基吡啶-3-甲腈和氯丙酮、氯乙酸乙酯、ω-溴苯乙酮和氯乙腈中的每一种合成。这些化合物可以方便地转化为新型吡啶并[4',5':4,5]噻吩并[3,2-d]嘧啶。此外,2,3-二氢-1,3,4-噻二唑由腙酰卤化物和2-苯并呋喃-2-基-3-(苯基氨基)-3-硫代丙腈合成。产品的结构已通过元素分析、光谱数据研究和可能的替代合成来阐明。新合成的化合物针对微生物进行了测试。
