Abstract

This minireview highlights known methods for the synthesis of azachromones and azachromanones, including the earliest and the latest examples of their synthesis. Methods considered for constructing azachromone or  azachromanone system include intramolecular heterocyclization, deprotection–cyclization, spirocyclization, cyclization–aromatization, Ullman-type O-arylation, and C–H activation of pyridine N-oxides.
