The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 5,5′-Dimethyl-2,2′-bipyridine(SMILESS: CC1=CN=C(C=C1)C1=NC=C(C)C=C1,cas:1762-34-1) is researched.Reference of 5-Fluoro-2-methylpyrimidin-4-amine. The article 《Dual Cobalt and Photoredox Catalysis Enabled Redox-Neutral Annulation of 2-Propynolphenols》 in relation to this compound, is published in Advanced Synthesis & Catalysis. Let’s take a look at the latest research on this compound (cas:1762-34-1).
A hydroxyl-assisted, organophotoredox/cobalt dual catalyzed annulation of 2-propynolphenols I [R1 = H, R2 = H, F, Cl, Br, MeO2C, Me; R1 = Cl, R2 = H; R1 = R2 = F; R3 = R4 = Me, Ph, 4-FC6H4, 3-F3CC6H4, etc.; R3 = Ph, R4 = Me, 4-ClC6H4, 2-FC6H4, 4-F3CC6H4, 2-thienyl, etc.; R3 = 4-FC6H4, R4 = 4-MeOC6H4; R3R4 = (CH2)5] to form 2-(hydroxymethyl)benzo[b]furans II has been developed by employing 1,2,3,5-tetrakis(carbazol-9-yl)-4,6-dicyanobenzene (4CzIPN) as photosensitizer and CoCl2(PPh3)2/5,5′-dimethyl-2,2′-bipyridine as cobalt catalytic precursor. Various substrates and functional groups were tolerated. The practical applications of this reaction were further demonstrated by enlarged gram-scale and various derivations for complex heterocycles. Primary mechanistic studies suggested the involvement of cobalt-hydride mediated hydrogen atom transfer (HAT) process.
There is still a lot of research devoted to this compound(SMILES：CC1=CN=C(C=C1)C1=NC=C(C)C=C1)Recommanded Product: 5,5′-Dimethyl-2,2′-bipyridine, and with the development of science, more effects of this compound(1762-34-1) can be discovered.
