Abstract

[Ce(l-Pro)₂]₂ (Oxa) was used as a recyclable heterogeneous catalyst under mild conditions for the preparation of 2-aryl-2,3-dihydroquinazolin-4(1H)-one derivatives. The one-pot protocol proceeds in ethanol using anthranilamide with several aldehydes at 50–55 °C. The catalyst can be recycled and reused three cycles without significant loss of catalytic activity.

用作多相催化剂的可回收[Ce（1-Pro）2] 2（Oxa）：在乙醇中一锅法合成2,3-二氢喹唑啉-4（1H）-酮

摘要

[Ce（1- Pro）₂ ] ₂（Oxa）在温和条件下用作可回收的多相催化剂，用于制备2-芳基-2,3-二氢喹唑啉-4（1 H）-一衍生物。一锅法在乙醇中使用邻氨基苯甲酰胺和几种醛在50–55°C下进行。该催化剂可以循环使用和再利用三个循环，而不会显着降低催化活性。
