摘要

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-azanaphthancenequinone derivatives which are key intermediates in the preparation of mitoxanthrone analogues.
