A one-pot oxidative cyclization of primary alcohols with o-aminobenzamides to quinazolinones was successfully achieved using [Cp*IrCl2](2) (Cp* = pentamethylcyclopentadienyl) as a catalyst under hydrogen transfer conditions.
plays an important role in forming the presence of intramolecularhydrogen bonds. The chemical shift of the Naryl-H downfield changes obviously, due to the formation of intramolecularhydrogen bonds and the deshielding effect of oxygen, and the neighboring C–H is activated and shows downfield protonic signal too. The presence of intramolecularhydrogen bonds probably provides the explanation for the transformation
