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.

Abstract

An efficient method has been developed for the preparation of a-aminophosphonates by using zinc di(L-prolinate) as a catalyst under mild reaction conditions. The method has the advantages of high yields, short reaction times, and easy workup conditions. [ABSTRACT FROM AUTHOR]
