DMSO as a dual carbon synthon in one-pot tandem synthesis of <i>N</i>-alkylated quinazolinones from anthranilamides and acetophenones

Abstract

DMSO-assisted approach for the synthesis of N -alkylated quinazolinones from readily available 2-aminobenzamide and aryl methyl ketones has been developed. DMSO played a dual role, acting as a solvent as well as a dual carbon synthon, making this process an environmentally benign approach.
