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 Rhodium-Catalyzed Asymmetric Allylic Substitution with Boronic Acid Nucleophiles, published in 2006-09-28, 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.
An enantio-, regio-, and diastereoselective rhodium(I)-catalyzed desymmetrization of a meso-cyclic allylic dicarbonate with organoboronic acid nucleophiles is described. The rhodium(I) catalyst formed in situ from [Rh(cod)OH]2 and Xyl-P-PHOS allowed the SN2′ allylic substitution product to be obtained with a range of arylboronic acids in enantiomeric excesses of up to 92% with regioselectivities of up to >20:1.
Here is a brief introduction to this compound(221012-82-4)HPLC of Formula: 221012-82-4, if you want to know about other compounds related to this compound(221012-82-4), you can read my other articles.
