Preparation and Application of Highly Efficient and Reusable Nanomagnetic Catalyst Supported with Sulfonated-Hexamethylenetetramine for Synthesis of 2,3-Dihydroquinazolin-4(1H)-Ones

Abstract

In this work, a magnetic nanoparticle supported with sulfonated-hexamethylenetetramine (SCMNPs-Pr-HMTA-SO₃H) as a new catalyst was used for the synthesis of new products of 2,3-dihydroquinazolin-4(1H)-ones. This protocol has highlighted advantages including easy purification, reusability, high thermal and chemical stability of catalyst, high selectivity, and high efficiency.
