of ten differnt α-mesitylacetophenones to 2-indanols in crystallinestate and as zeolite inclusion complexes has been examined. In the systems examined the chiral auxiliary functioned better within zeolites than in crystals. Crystal structure analysis of three α-mesitylacetophenones revealed that the low chiral induction in the crystallinestate is either due to the presence of conformational isomerism
