Irradiation in the crystalline state of salts formed between α-mesitylacetophenone-p-carboxylic acid and a variety of optically pure amines—the so-called ‘ionic chiral auxiliary’ approach to asymmetric synthesis—leads to the corresponding 2-indanol in excellent yield and in high enantiomeric excess. X-Ray crystallography reveals the source of the enantioselectivity.
