presence of active methylene compounds (AMCs) to produce substituted quinolines in high yields. The conditions are mild enough to tolerate a wide range of functionality in both reacting partners and promote reactions not only with phenyl and benzyl ketones, but also with β-keto-esters, β-keto-nitriles, β-keto-sulfones and β-diketones. The reaction of 2-nitroaromatic ketones with unsymmetrical AMCs is
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
