In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Asymmetric hydrogenation of quinolines with high substrate/catalyst ratio, published in 2007-02-14, which mentions a compound: 221012-82-4, Name is (R)-2,2′,6,6′-Tetramethoxy-4,4′-bis(diphenylphosphino)-3,3′-bipyridine, Molecular C38H34N2O4P2, HPLC of Formula: 221012-82-4.

The chiral diphosphinite ligand derived from (R)-1,1′-spirobiindane-7,7′-diol has been found to be highly effective in the Ir-catalyzed asym. hydrogenation of quinolines with high substrate/catalyst ratio (up to 5000) and high enantioselectivity (up to 94% ee).
