We report a mild, fast, highly efficient and eco-friendly protocol for the green synthesis of pyrrolo[2,3-d]isoxazoles and a new series of novel benzyl bis-pyrrolo[2,3-d]isoxazoles from nitro styrylisoxazoles in SnCl(2)-ionic liquid by reductive cyclization. These reactions were performed at ambient temperature which resulted in good yields in short reaction time, without requiring any organic solvent
我们报告了一种温和,快速,高效和环保的方案,用于从硝基硝基苯乙烯基恶唑中合成吡咯并[2,3-d]异恶唑和一系列新的新型苄基双吡咯并[2,3-d]异恶唑。 SnCl(2)离子液体的还原环化。这些反应在环境温度下进行,从而在短的反应时间内获得了良好的产率,而无需任何有机溶剂和催化剂。
