First photosensitized enantiodifferentiating polar addition: anti-markovnikov methanol addition to 1,1-diphenylpropene
Abstract
Enantiodifferentiating methanol addition to 1,1-diphenylpropene sensitized by chiral naphthalene(di)carboxylates gave optically active 1,1-diphenyl-2-methoxypropane in optical yields up to 27%, indicating the intervention of an intimately interacting exciplex or contact ion pair.
