Abstract
Herein, we describe a transformation of the oxo-function of a series of quinolin/pyridin/quinazolin-4-ones into 4-azido and thence into 4-amino derivatives in moderate yields by a very short and convenient new procedure using DPPA (diphenylphosphoryl azide) as reagent. A mechanism for this interesting new application of DPPA is suggested based on the identification of some of the intermediates.
