Electric Literature of C38H34N2O4P2. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: (R)-2,2′,6,6′-Tetramethoxy-4,4′-bis(diphenylphosphino)-3,3′-bipyridine, is researched, Molecular C38H34N2O4P2, CAS is 221012-82-4, about Rhodium-Catalyzed Asymmetric [2+2+2] Cycloaddition of 1,6-Enynes with Racemic Secondary Allylic Alcohols through Kinetic Resolution. Author is Suzuki, Shunsuke; Shibata, Yu; Tanaka, Ken.
It has been established that a cationic rhodium(I)/P-phos complex catalyzes the asym. [2+2+2] cycloaddition of 1,6-enynes R1CCCH2ZCH2CH(=CH2)R2 (R1 = Me, Ph, pentyl; R2 = H, Me) with racemic secondary allylic alcs. R3CH(OH)CH=CH2 to produce the corresponding chiral bicyclic cyclohexenes I, possessing three stereogenic centers, as a single diastereomer with excellent ee values. Mechanistic experiments revealed that the present cycloaddition proceeds through the kinetic resolution of the racemic secondary allylic alcs., in which one enantiomer preferentially reacts with the 1,6-enyne.
There is still a lot of research devoted to this compound(SMILES：COC(C=C1P(C2=CC=CC=C2)C3=CC=CC=C3)=NC(OC)=C1C4=C(OC)N=C(OC)C=C4P(C5=CC=CC=C5)C6=CC=CC=C6)Electric Literature of C38H34N2O4P2, and with the development of science, more effects of this compound(221012-82-4) can be discovered.
