Synthesis of benzonaphthofuroquinones and benzoylnaphthindolizinediones by reactions of flavonoids with dichlone under basylous, oxygenous and aqueous conditions: their cytotoxic and apoptotic activities

Abstract

Using flavonoids and dichlone as substrates, six benzonaphthofuroquinones and three benzoylnaphthindolizinediones were synthesized through common base-catalyzed method and a new method of combining base-catalyzed with O₂/H₂O exposing.
