Synthesis of 2-Aza-anthraquinone and 2-Azanaphthacenequinone 1-Chloro-derivatives as Key Intermediates for the Preparation of Antitumour Anthraquinone Analogues

Lithiation of 2-(2-chloro-4-pyridyl)-4,4-dimethyl-4,5-dihydro-oxazole and subsequent condensation with aromatic aldehydes provides a four-step synthesis of both 1-chloro-2-aza-anthraquinone and 1-chloro-2-azanaphthacenequinone derivatives which are key in
