Two complementary stereospecific synthetic approaches for the preparation of unsymmetrical ortho-substituted N-(4,4-diphenylbut-3-enyl) derivatives of nipecotic acid are described. Determination of the activity of the prepared compounds at the GAT-1 transporter highlighted differing SAR requirements of the E- and Z-phenyl rings, and led to the discovery of a compound with comparable potency to tiagabine. Some attempts to replace nipecotic acid with alternative novel amino acids are also described. (C) 2010 Published by Elsevier Ltd.
