A new series of benzo[6,7]cyclohepta[1,2‐d]triazolo[4,3‐a]pyrimidines 8a–l was synthesized via reaction of heterocyclic thione 4 or its methyl derivatives 10 with hydrazonoyl halides 5a–l. Also, reaction of compound 4 with a mixture of chloroacetic acid and aromatic aldehyde derivatives gave benzo[6,7]cyclohepta[1,2‐d]thiazolo[3,2‐a]pyrimidin‐3‐ones 12–14. The microanalyses and spectral data of the
通过杂环硫酮4或其甲基衍生物10与腙酰卤5a-l反应合成了一系列新的苯并[6,7]环庚[1,2-d]三唑并[4,3-a]嘧啶8a-l。此外,化合物 4 与氯乙酸和芳香醛衍生物的混合物反应得到苯并[6,7]环庚[1,2-d]噻唑并[3,2-a]嘧啶-3-酮12-14。合成化合物的微量分析和光谱数据与其分子结构完全一致。所有新合成的产物都针对 5α-还原酶进行了筛选,并且对所有化合物均显示出良好的 ED50 活性。
