Transition-Metal-Free One-Pot Synthesis of Naphthoquinonefuran Derivatives Through Sequential Nucleophilic Substitution–Nucleophilic Addition Reaction

“…The wide spectrum of biological activities has attracted widespread interest in the field of medicinal chemistry; therefore, much effort has been focused on the synthetic methods of naphthofuroquinone derivatives. Over the past decades, base-catalyzed, bromine-mediated, different annulations − (such as thermal cyclization, photoaddition, oxidative cycloaddition, Diels–Alder cycloaddition/aromatization, oxidative cyclization/isomerization), one-pot cascades, and transition-metal-catalyzed syntheses of the naphthofuroquinone skeleton have been reported.…”
