摘要：
Four methods of asymmetric induction in the cis,trans-photoisomerization of 2 beta,3 beta diphenylcyclopropane-1 alpha-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.
