Abstract

A copper-catalyzed domino addition/cyclization reaction was developed to synthesize novel benzoselenazole-linked 1,2,3-triazole and tetracyclic fused 12H-benzo[4,5]selenazole[2,3-b]quinazolin-12-one derivatives from isoselenocyanates. This domino reaction efficiently constructed multiple new chemical bonds in a single step, forming either four (one C–Se and three C–N) or three (one C–Se and two C–N) bonds. The reaction offers several key advantages, including mild conditions, broad substrate compatibility, and straightforward and safe operation. It presents a new method for synthesizing N, Se-containing polycyclic compounds, which have potential interest in medicinal chemistry. Notably, some of the synthesized compounds exhibited anticancer activity with IC50 values below 20 μmol L–1 against T24 human bladder cancer cells.

铜催化异硒氰酸酯的多米诺环:结构多样的N, se -双杂环和融合杂环化合物的途径
采用铜催化的多米诺加成/环化反应,从异硒氰酸酯中合成了新型苯并硒唑- 1,2,3-三唑和四环融合的12h -苯并[4,5]硒唑[2,3-b]喹唑啉-12- 1衍生物。这种多米诺骨牌反应在一步中有效地构建了多个新的化学键,形成四个(一个C-Se和三个C-N)或三个(一个C-Se和两个C-N)键。该反应具有几个关键的优点,包括温和的条件,广泛的底物相容性,简单和安全的操作。提出了一种合成含氮、硒多环化合物的新方法,在药物化学中具有潜在的应用价值。部分化合物对T24人膀胱癌细胞的IC50值低于20 μmol L-1。
