Pyrrolotriazines and related fused azaheterocycles have high potential for the synthesis of bioactive compounds, especially as a purine base isoster in carbon linked nucleosides. Although many structurally related compounds have already been synthesized and used in medicinal chemistry, pyrrolo[1,3,5]triazines have barely been described. The present work describes the synthesis of such heterocycles
吡咯并三嗪和相关的稠合氮杂杂环化合物具有很高的合成生物活性化合物的潜力,尤其是作为碳连接核苷中的嘌呤碱基等排物。尽管已经合成了许多结构相关的化合物并用于药物化学,但几乎没有描述吡咯并[1,3,5]三嗪。本工作描述了通过2-氨基-3-乙氧基羰基吡咯与乙氧基羰基异(硫代)氰酸酯的缩合来合成这些杂环。在对所获得的稠合吡咯的简要反应性研究中,证明了O-和S-烷基化,酯水解以及6位区域选择性溴化。
