[ 1 ] - Thiamine hydrochloride (vitamin B1) as an efficient catalyst for the synthesis of 4-(3H)-Quinazolinone derivatives using grinding method.
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.Qu...
