Confined space and cations enhance the power of a chiral auxiliary: photochemistry of 1,2-diphenylcyclopropane derivatives.
Alkali ion-exchanged Y-zeolites significantly enhance asymmetric induction in the photoisomerization of a number of cis-1,2-diphenylcyclopropane derivatives containing a distant chiral auxiliary.
