Enantio- and Diastereodifferentiating cis,trans-Photoisomerization of 2β,3β-Diphenylcyclopropane-1α-carboxylic Acid Derivatives in Organized Media

Four methods of asymmetric induction in the cis,trans-photoisomerization of 2β,3β-diphenylcyclopropane-1α-carboxylic acid derivatives were studied. Best results (ca. 80% de) were obtained by irradiation of chiral esters, amides, and salts in NaY and LiY zeolites and in the pure crystalline state.
