Abstract

Abstract : A facile visible light promoted [4 + 2] annulation reaction from readily available starting materials using an organo-photocatalyst gave anthracenone-furans with up to 95% yield in one-pot. Abstract : A facile visible light promoted approach to anthracenone-furans from readily available 2, 3-dibromonaphthoquinones and phenylbenzofurans via a formal Diels Alder reaction is reported. This reaction involves wavelength-selective agitation of 4CzIPN, energy transfer to quinones, recombination of 1, 6-biradicals and elimination to give anthracenone-furans in good to excellent yields in one pot.
