Abstract:An alternative asymmetric synthesis of ropivacaine and analogues employing the ‘cation pool’ strategy and host/guest supramolecular co-catalysis approach is presented. In this study, chiral auxiliaries, several soft nucleophiles as well as one-pot conditions for anodic oxidation, followed by nucleophilic addition, have been applied.
Keywords:Ropivacaine  Levobupivacaine  Anodic oxidation  Cation pool  Supramolecular complex
