A novel, one-pot, and three-component synthesis of 4(3H)-quinazolinones is described. Benzyl halides are oxidized to aldehydes under mild Kornblum conditions then undergo a three-component reaction with isatoic anhydride and primary amines to produce 4(3H)-quinazolinones in excellent yields. benzyl halides - Kornblum oxidation - isatoic anhydride - amines - 4(3H)-quinazolinones - multicomponent reactions
