Magnetic Fe3O4 nanoparticles as a heterogeneous catalyst were found to be efficient for the synthesis of a series of pyrrole and indole derivatives using three-component reactions of primary amines, 1,3-dicarbonyl compounds, and activated acetylenic compounds under solvent-free conditions at room temperature. The present protocol offers the advantages of clean reaction, short reaction time, high yield
发现磁性Fe 3 O 4纳米颗粒作为非均相催化剂可有效地在无溶剂条件下使用伯胺,1,3-二羰基化合物和活化炔属化合物的三组分反应合成一系列吡咯和吲哚衍生物在室温条件下。本方案提供了清洁反应,短反应时间,高收率,易于纯化和催化剂负担能力的优点。
