  First stereoselective synthesis of potassium aeschynomate and its no-natural stereomers

  摘要：

  The synthesis of potassium aeshynomate and its non-natural stereomers was achieved using the Sharpless catalytic asymmetric dihydroxylation of (Z) or (E) vinylogous glycine as the key step. The resulting gamma-amino alpha, beta-dihydroxyester stereomer was deprotected and coupled with the caffeic acid to afford stereoselectively potassium aeshynomate or its stereomers. A detailed study of the NMR data of the different stereomers is reported that corrects the literature data. (c) 2005 Elsevier Ltd. All rights reserved.
