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

a series of α-mesitylacetophenone derivatives into 2-indanols via δ-hydrogen abstraction has been investigated in the solid state. A correlation between solid-state reactivity and crystal structure has been established for this type of reaction. For the seven compounds whose crystal structures were determined, the average value of d (CO⋯H distance) and L (CO⋯CH3 distance) were 2.77±0.04 Å and 3.42±0
