Abstract

MCM-41-SO3H, ordered mesoporous silica material MCM-41 with covalently anchored sulfonic acid groups located inside the mesochannels, was used as an acid catalyst for the rapid and ‘green’ synthesis of 2,3-dihydroquinazolin-4(1H)-one derivatives under solvent-free condition. This novel synthetic method offers several advantages, such as excellent yields, simple procedure, short reaction times, and mild reaction conditions.
