Abstract

A novel and efficient Mn(III)-mediated oxidative radical cascade reaction of 1-(azidomethyl)-2-isocyanoarenes with organoboronic acids is reported. The single electron oxidation of a commercially available organo boronic acid in the presence of a mild oxidant, Mn(OAc)3·2H2O, resulted in moderate yields of the corresponding quinazoline derivatives.

Abstract

Mn-TBHP mediated oxidative radical cyclization of 2-(azidomethyl)phenyl isocyanides using methyl carbazate has been described. This procedure is realized through a cascade radical addition and aromatization process with high atom economy to furnish various heterocyclic C2 diversified quinazoline-2-carboxylate derivatives.
