The first supramolecular photosensitization of enantiodifferentiating bimolecular reaction: anti-Markovnikov photoaddition of methanol to 1,1-diphenylpropene sensitized by modified β-cyclodextrin

Enantiodifferentiating polar photoaddition of methanol to 1,1-diphenylpropene included and sensitized by cyanonaphthalene-modified β-cyclodextrin was examined for the first time to give optically active anti-Markovnikov adduct with accompanying inversion of the chiral sense of the photoproduct by temperature, which is entropic in origin.
