α-Hydroxy acid as an aldehyde surrogate: metal-free synthesis of pyrrolo[1,2-<i>a</i>]quinoxalines, quinazolinones, and other N-heterocycles<i>via</i>decarboxylative oxidative annulation reaction

Abstract

-butyl hydrogen peroxide), and further condensation with various amines, followed by intramolecular cyclization and subsequent oxidation to afford the corresponding quinoxalines, quinazolinones derivatives in moderate to high yields.
