异喹啉二酮骨架是一种重要的有机合成砌块, 广泛存在于生物碱、天然产物和药物中. 提供了一种非金属催化构建异喹啉二酮骨架结构的新方法. 机理研究表明, 该反应经历了一个自由基过程: 在四丁基碘化胺催化作用下, 肼化合物质子被逐步攫取生成烷氧羰基自由基, 随后对活化烯烃进行自由基加成反应, 进一步环化形成异喹啉二酮骨架. 该方法具有反应条件温和、底物普适性广、环境友好等特点, 为合成含异喹啉二酮骨架分子结构提供了一种新途径.

The isoquinolinedione skeletons are important building blocks, which have been widely present in plant alkaloids, natural products and pharmaceuticals. In this paper, a novel method to construct isoquinolinedione framework was developed, which can be easily operated under metal-free conditions. In the presence of tetrabutylammonium-iodide catalyst, hydrogen atoms were abstracted step by step from carbazate to generate methoxycarbonyl radical which followed by radical addition/cyclization reaction leading to isoquinolinedione. The presented methodology will provide new strategies for construct isoquinolinedione-type products, which has advantages of simple operation, mild reaction conditions, and environmentally benign.

Key words: isoquinolinedione skeleton, metal-free, tetrabutylammonium-iodide, radical addition/cyclization
