9-tetrahydrothieno[2,3-c][2,7]naphthyrid ine-2-substituted (VIb, VIe, VIi) compounds as a precursor to create original heterocyclic moieties, namely: pyrimidothienonaphthyridino and pyridothieno naphthyridino in compounds (VII, VIII, IX, X, and XIa, b). Elemental analysis and spectral techniques (Fourier Transform Infrared (FT-IR), Nuclear magnetic resonance (1H NMR, 13C NMR, and mass spectrum)) were affirmed to validate
摘要 近年来,2,7-萘啶的生物用途引起了极大的关注。为此,我们合成了一系列新型 2,7-萘啶衍生物,并在本研究中探索了它们的光谱和生物学特性。通过 1-甲基哌啶-4-酮 ( I ) 与 CS 2、丙二腈和三乙胺反应制备取代的四氢-1 H-噻吩并 [3,4- c ] 吡啶-4-甲腈 ( III )。缩合的硫吡喃 ( III ) 通过与吗啉反应转化为三巯基-7-甲基-1-吗啉代-5,6,7,8-四氢-2,7-萘啶-4-甲腈( IV )。复合(四) 被用作一系列杂环化合物的起始剂,例如噻吩并[2,3- c ][2,7]萘啶部分 ( VIa – i )。我们使用 1рamino-7-methyl-5-morpholino-6,7,8,9-tetrahydrothieno[2,3- c ][2,7]naphthyridine-2-取代 ( VIb , VIe , VIi ) 化合物作为前体创造原始
