Abstract

Herein we explore facile synthesis of 4-(3H)-Qunazolinone derivatives, achieved by the cyclocondensation of anthranilic acid, aromatic amines and triethyl orthoformate in presence of thiamine hydrochloride (Vitamin B1) as a catalyst, using grinding method. This protocol offers several advantages such as reusability of catalyst, excellent yield, shorter reaction time and economic availability.Quinazolinone derivatives are one of the most important class of biodynamic heterocycles due to their wide range of biological activities such as anticancer [1], antitubercular agent [2], anti-inflammatory and antioxidant [3], anticonvusant agent [4], antimicrobial [5], antitumor [6], ACHE inhibitor [7], antiviral [8] and calcilytic activities [9-10]. Owing to the broad range of pharmacological, biological activities and development of new method for synthesis of quinazolinones derivative is still desirable.
