Application of SBA-Pr-SO3H in the synthesis of 2,3-dihydroquinazoline-4(1H)-ones: characterization, UV–Vis investigations and DFT studies

An efficient one-pot synthesis of 2,3-dihydroquinazoline-4(1 H )-one derivatives 4a–l is described using SBA-Pr-SO 3 H as a heterogeneous acid catalyst. The present methodology resulted in various derivatives of 2,3-dihydroquinazoline-4(1 H )-one in good yield via a three-component reaction of isato...

Summary:An efficient one-pot synthesis of 2,3-dihydroquinazoline-4(1 H )-one derivatives 4a–l is described using SBA-Pr-SO 3 H as a heterogeneous acid catalyst. The present methodology resulted in various derivatives of 2,3-dihydroquinazoline-4(1 H )-one in good yield via a three-component reaction of isatoic anhydride, aldehydes and ammonium acetate. SBA-Pr-SO 3 H played a significant role as an efficient mesoporous catalyst due to its pore size of 6 nm. Additionally, UV–Vis spectrum of the products was studied in order to investigate their application as UV absorbers.
