This is the first report of supportingzinccation on ƛ‐carrageenan/Fe3O4 magneticnanoparticles. The structural and magnetic properties of this hybrid (Zn2+/ƛ‐carrageenan/Fe3O4 nanoparticles) were identified using various techniques. This green and efficientcatalyticsystem was applied in the synthesis of biologically important quinolines. The products were obtained in good to high yields (52–95%)
这是第一个在ƛ-卡拉胶/ Fe 3 O 4磁性纳米粒子上支持锌阳离子的报告。使用各种技术鉴定了这种杂化物(Zn 2 + /β-卡拉胶/ Fe 3 O 4纳米颗粒)的结构和磁性。这种绿色高效的催化体系被用于合成生物学上重要的喹啉。从一锅法反应过程中获得的产品,收率高至高(52-95%),涉及芳族醛,可烯醇化醛和苯胺衍生物。我们的方法具有许多优点,例如反应条件温和,易于后处理,使用可重复使用的磁性催化剂和高收率的产品。
New Pyridinium-Based Ionic Liquid as an Excellent Solvent–Catalyst System for the One-Pot Three-Component Synthesis of 2,3-Disubstituted Quinolines
The synthesis of a variety of 2,3-disubstituted quinolines has been achieved successfully via a one-potthree-component reaction of arylamines, arylaldehydes and aliphatic aldehydes in the presence of butylpyridinium tetrachloroindate(III), [bpy][InCl4], ionicliquid as a green catalyst and solvent. Mild conditions with excellent conversions, and simple product isolation procedure are noteworthy advantages
