The concise synthesis of a potent thrombin inhibitor was accomplished by a mild lactone aminolysis between an orthogonally protected bis-benzylic amine and a diastereomerically pure lactone. The lactone was synthesized by the condensation of l-proline methyl ester with an enantiomericallypure hydroxy acid, which in turn was synthesized by a highly stereoselective (>500:1 er) and productive (100000:1
