A facile synthesis of quinazolin-4(3H)-ones possessing carbon substituents at positions 2 and 3 has been developed. Key to the synthesis is a tandem strategy involving introduction of a 2-substituent and construction of the quinazolinone framework via C-nucleophilic addition to the carbodiimide cumulenic carbon followed by intramolecular nucleophilic substitution by the newly formed NH moiety at the proximal ester group.
