  A chiral beta-amino acid containing three contiguous chiral centers was synthesized efficiently in 11 steps, employing enantio-enriched beta-ketoester as a key intermediate, via stereoselective catalytic hydrogenation of the corresponding enamide. Stereoselective 1,4-addition of a methyl group and protonation were key to the preparation of the desired acid 12. Mild and efficient reaction conditions were applied to the enamine formation and protection to avoid epimerization at C-4 of compounds 13 and 14. The final compound was found to display potent affinity for the alpha(2)delta-protein that is a recognized drug target for the treatment of a variety of diseases. (C) 2009 Elsevier Ltd.
