[反应：见正文] 研究了2β，3β-二苯基环丙烷-1α-羧酸衍生物的顺式、反式光异构化的四种不对称诱导方法。通过辐照 NaY 和 LiY 沸石中纯结晶状态的手性酯、酰胺和盐获得了最佳结果（约 80% de）。
[reaction: see text] Four methods of asymmetric induction in the cis, trans-photoisomerization of 2beta, 3beta-diphenylcyclopropane-1alpha-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.
