Photochemical Reaction of 1,2-Naphthoquinone toward Enantioselective Synthesis of γ-Rubromycin: Viability Dependence on Chromophore

Abstract

AbstractAiming at the enantioselective total synthesis of γ-rubromycin, we reported the photochemical reaction of 1,2-naphthoquinone as a promising solution to otherwise-difficult enantiocontrol of the single spiroacetal stereogenic center. The present study examined the applicability of this approach to more functionalized substrates, which revealed viability dependence on the chromophore structure differing in the position and number of methoxy substituents.
