Resolution of (±)-nipecotic acid ((±)-3-piperidinecarboxylic acid) by separation of palladium(II) diastereomers containing orthometallated (S)-(-)-1-[1-(dimethylamino)ethyl]naphthalene

Abstract

An efficient resolution of (±)-nipecotic acid has been achieved by the fractional crystallization of internally diastereomeric palladium(II) complexes containing the chelated carboxylate and orthometallated (S)-(-)-1-[1-(dimethylamino)ethyl]naphthalene. Show more
