Photoredox Reaction Of Naphthoquinone C-Glycoside Revisited: Insight Into Stereochemical Aspect

Insights into the naphthoquinone photoredox reactions have been gained from the reactions of a C-glycosyl naphthoquinone. The retentiveness comes from the balance of the lifetime of intermediary zwitterionic species relative to the conformational change to bring about the stereo-mutating C-C bond rotation.
