Abstract
A new approach has been evaluated for the preparation of solution free and polymer supported chiral bicyclic amino alcohols. This strategy involves the use of readily available starting materials and allows chiral ligands characterised by the bispidine core. bearing a stereogenic centre beta to one of the nitrogen atoms to be obtained. The first results obtained from the application of these ligands in the asymmetric addition reaction of diethylzinc to benzaldehyde are discussed. (C) 2003 Elsevier Ltd. All rights reserved.
