Some 2-alkyl-1,2-dihydroquinoline and some 2-aryl-1,2-dihydroquinoline were obtained by enantioselective addition of methyl-, butyl-, phenyl- and 1-naphthyllithium on quinoline. Bisoxazolines were used as external chiral ligands, giving enantiomeric excess up to 79%. The ligand could be used in catalytic amounts without significant loss of enantioselectivity.
A highly efficient kinetic resolution of racemic 2-substituted 1,2-dihydroquinolines via asymmetric Cu-catalyzed borylation has been realized for the first time. Under mild conditions, a variety of chiral 3-boryl-1,2,3,4-tetrahydroquinolines containing two vicinal stereogenic centers as well as the recovered 2-substituted 1,2-dihydroquinolines were afforded after 30 minutes in high yields with up to
