Recyclable [Ce(l-Pro)2]2 (Oxa) used as Heterogeneous Catalyst: One-Pot Synthesis of 2,3-Dihydroquinazolin-4(1H)-ones in Ethanol
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(1 H )-one derivatives. The one-pot protocol proceeds in ethanol using anthranilamide with several aldehydes at 50–55 °C. The catalyst can be r...
