Synthesis of quinazolinone scaffolds via a zinc(ii)-stabilized amidyl radical-promoted deaminative approach†

Abstract

Herein, we report a solely ligand centered redox controlled protocol, utilizing a bench 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.
