Bifunctional C2-symmetric 7,7′-dihydroxymethyl-8,8′-biquinolyl (2) was synthesized in short steps via (i) Cu/Pd-catalyzed homo coupling of 7-methyl-8-bromoquinoline and (ii) Pd(II)-catalyzed double C-H oxidation. Axial chirality of 2 and its synthetic precursor 7,7′-dimethyl-8,8′-biquinolyl (3) is stable. Optically active 2 was obtained through separation of racemic 2 by chiral column HPLC or Pd(II)-catalyzed double C-H oxidation of optically active 3. The absolute stereochemistry of enantiomers of 2 and 3 was determined using the exciton chirality method.

The bromination of quinoline and substituted quinolines with N-bromosuccinimide in concentrated H2SO4 takes place exclusively in the homocyclic part.Bromo-substituted quinolines can be obtained by this method.The bromination products were identified by PMR spectroscopy.The differences among the mono-, di-, and trisubstituted (in the benzene ring) compounds were established on the basis of the type of spectrum of the protons of the homocyclic part of the molecule.The compositions of the reaction mixtures were studied by GLC.
