Enantioselective Synthesis of Endocyclic β-Amino Acids with Two Contiguous Stereocenters via Hydrogenation of 3-Alkoxycarbonyl-2-Substituted Quinolines
Abstract An enantioselective iridium-catalyzedhydrogenation of 3-alkoxycarbonyl-2-substituted quinolinederivatives is described. This methodology provides a convenient route to enantiopure endocyclic β-amino acids with two contiguous stereocenters with up to 90% ee. An enantioselective iridium-catalyzedhydrogenation of 3-alkoxycarbonyl-2-substituted quinolinederivatives is described. This methodology
