Abstract:

A new, facile, cost effective, and eco-friendly protocol is reported for the synthesis of 2,3-dihydroquinazoline-4-(1H)-ones exploring tannic acid as a novel, inexpensive, andbiodegradable catalyst. A variety of dihydroquinazolins were prepared from aromatic aldehydesand anthranilamide using catalytic amount of tannic acid under solvent free conditions.Operational simplicity, high yield, and high atom-economy are the important features of thisprotocol.

Sulfonated Porous Carbon (SPC): An efficient and recyclable solid acid catalyst for one-pot three-component synthesis of 2,3-dihydroquinazolin-4(1H)-ones under solvent-free conditions

A simple and efficient procedure has been developed for the synthesis of 2,3-dihydroquinazolin-4(1H)-ones derivatives under solvent-free conditions. This method uses the condensation of isatoic anhydride, aldehydes, and amines in the presence of a catalytic amount Sulfonated Porous Carbon (SPC). One of the important advantages of the new method is that the SPC could be recycled and reused.
