Abstract

Irradiation in the crystalline state of salts formed between alpha-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. (C) 1999 Elsevier Science Ltd. All rights reserved.
