Oxidation of the title compounds yields N-nitrenes which rect intramolecularly with electron-rich aryl groups via 7-membered transition states; substituent effects are in accord with an electrophilic aromatic substitution rather than concerted addition.

stable zinc compound, for the efficient coupling of o-amino amides/esters with nitriles to afford diverse quinazolinone scaffolds and their synthetic utility was showcased via post-modification to access therapeutically relevant compounds. Importantly, mechanistic probes established the reaction pathway that proceeds via aminyl radical.
