Lei, Bai-Lin; Zhang, Qing-Song; Yu, Wei-Hua; Ding, Qiu-Ping; Ding, Chang-Hua; Hou, Xue-Long published an article about the compound: (R)-2,2′,6,6′-Tetramethoxy-4,4′-bis(diphenylphosphino)-3,3′-bipyridine( cas:221012-82-4,SMILESS: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 ).Safety of (R)-2,2′,6,6′-Tetramethoxy-4,4′-bis(diphenylphosphino)-3,3′-bipyridine. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:221012-82-4) through the article.
The kinetic resolution of 2-substituted-2,3-dihydro-4-pyridones was realized via a Pd-catalyzed allylic substitution reaction using a com. available (S)-P-Phos as a ligand, affording optically active dihydropyridones and C-allylated dihydropyridones in high yields and good enantioselectivities with the S-factor up to 43. With this protocol, a catalytic asym. total synthesis of indolizidine (-)-209I (I) was realized for the first time.
