Our aim here is the synthesis of 4‐(2‐thienyl or 2‐furyl)‐6‐pyridin‐3‐ylthieno[2,3‐b]pyridin‐3‐amines 6a, 6b, 6c, 6d, 6e, 6g, 6h, 6i, 6j, 6k, 6l, 6m, 6n,via 6‐(alkyl‐thio)‐4‐(2‐thienyl or 2‐furyl)‐2,3′‐bipyridine‐5‐carbonitriles 5a, 5b, 5c, 5d, 5e, 5i, 5j, 5k, 5l, 5m. The structures of all newly synthesized heterocyclic compounds were elucidated by considering the data of IR, 1H‐NMR, mass spectra, as
1-吡啶-3-基-3-(2-呋喃基2-噻吩基)丙-2-烯-1-酮1A,1B与2- cyanoethanethioamide反应2,得到相应的4-(噻吩-2-基或呋喃-2-基)-6-硫烷基-2,3'-联吡啶-5-腈3a,3b。化合物的合成潜力图3a,3b中进行了在本研究中通过他们的反应研究用含有化合物的几种活性卤素图4a,图4b,图4c,图4d,图4e,4f中,4克,4H,5,5a中,5b。我们的目标是合成4-(2-噻吩基或2-呋喃基)-6-吡啶-3-基噻吩并[2,3 - b ]吡啶-3-胺6a,6b,6c,6d,6e,6g,通过6-(烷基硫基)-4-(2-噻吩基或2-呋喃基)-2-3,3'-联吡啶-5-腈5a,5b,5c通过6h,6i,6j,6k,6l,6m,6n,5d,5e,5i,5j,5k,5l,5m。考虑到IR,1 H-NMR,质谱数据以及元素分析数据,阐明了所有新合成的杂环化合物的
