Get PDFExpeditious synthesis of 2,3-dihydroquinazolin-4(1<i>H</i>)-ones in aqueous medium using thiamine hydrochloride (VB<sub>1</sub>) as a mild, efficient, and reusable organocatalyst
No full text<p>A simple and straightforward synthesis of 2,3-dihydroquinazolin-4(1<i>H</i>)-ones is developed by reacting anthranilamide with various aldehydes or ketones under mild reaction conditions, using thiamine hydrochloride as a cost-effective, readily available, and green catalyst in water. Simple purification process, high yields within short reaction time, wide substrate scope, operational simplicity, and reusability of the catalyst up to three cycles enrich the applicability of the protocol.</p
