concise synthesis of a stereochemically rich hNK-1 receptorantagonist is described. The synthesis is highlighted by an S(N)2 reaction of an enantiomericallypure alpha-alkoxy sulfonate (orthogonally protected butane triol), which was prepared by utilizing salen-mediated hydrolytic kinetic resolution technology. A stereocontrolled acetalization was employed to connect two enantiomericallypure fragments
