A hitherto unreported route for the synthesis of anthranilate esters is demonstrated using 2-nitrobenzaldehyde, malonitrile and an alcohol or amine via a metal and oxidant free multicomponent reaction (MCR) strategy.

Two-stage reaction of methyl anthranilate with aryl(alkyl) isocyanates in keeping with the quantum-chemical calculations and XRD analysis resulted in 3-aryl(alkyl) quinazoline-2,4(1H,3H)-diones that by treatment with alkyl halides, phenacyl bromides, esters and amides of chloroacetic acid were converted into the corresponding 1-alkyl derivatives.
