  Ephedrine derived reusable chiral auxiliary for the synthesis of optically pure 3-hydroxy-4-aryl-β-lactams

  摘要：

  The diastereoselective synthesis of carious beta-lactams has been achieved using a chit-at acid auxiliary derived from (-)-ephedrine. An efficient acid-catalyzed cleavage of the chiral auxiliary from these beta-lactams to afford 3-hydroxy-4-aryl-cis-beta-lactams. which are precursors for analogues Of the taxol side chain, is described.
