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 New diphosphite ligands for enantioselective asymmetric hydroformylation, published in 2007-07-02, which mentions a compound: 119707-74-3, Name is (S)-3,3′-Dibromo-1,1′-bi-2-naphthol, Molecular C20H12Br2O2, Electric Literature of C20H12Br2O2.
A series of new diphosphite ligands were easily prepared from BINOL derivatives Moderate enantioselectivities (≤80% ee) and excellent regioselectivities (branched/linear ≤ 98/2) were achieved in the Rh-catalyzed asym. hydroformylation of vinyl acetate.
This literature about this compound(119707-74-3)Electric Literature of C20H12Br2O2has given us a lot of inspiration, and I hope that the research on this compound((S)-3,3′-Dibromo-1,1′-bi-2-naphthol) can be further advanced. Maybe we can get more compounds in a similar way.
