Compound: (R)-2,2′,6,6′-Tetramethoxy-4,4′-bis(diphenylphosphino)-3,3′-bipyridine(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,cas:221012-82-4) is researched.Application In Synthesis of (R)-2,2′,6,6′-Tetramethoxy-4,4′-bis(diphenylphosphino)-3,3′-bipyridine. The article 《Rhodium-Catalyzed Asymmetric 1,4-Addition of Arylboronic Acids to Coumarins: Asymmetric Synthesis of (R)-Tolterodine》 in relation to this compound, is published in Organic Letters. Let’s take a look at the latest research on this compound (cas:221012-82-4).

Rhodium-catalyzed asym. 1,4-addition of arylboronic acids R1B(OH)2 (R1 = Ph, 4-MeC6H4, 3-MeC6H4, 4-ClC6H44, 4-MeOC6H4) to coumarins I (R = 6-Me, H, 6-MeO2C, 8-MeO) proceeded with high enantioselectivity in the presence of a rhodium catalyst (3 mol %) generated from Rh(acac)(C2H4)2 and (R)-Segphos to give the corresponding (R)-4-arylchroman-2-ones II in over 99% ee. This asym. reaction was applied to the synthesis of (R)-tolterodine.
