A formal catalytic enantioselective cross-dehydrogenative coupling of saturated ethers with diverse carboxylic acid derivatives involving an initial oxidative acetal formation, followed by nickel(II)-catalyzed asym. alkylation. The one-pot, general and modular method exhibited wide compatibility of a broad range of saturated ethers not only including prevalent THF and tetrahydropyran but also including medium- and large-sized cyclic moieties and acyclic ones with excellent enantioselectivity and functional group tolerance. The application in the rapid preparation of biol. active mols. that are difficult to access with existing methods was also demonstrated. In addition to this study using (S)-5,5′-Bis(diphenylphosphino)-4,4′-bi-1,3-benzodioxole, there are many other studies that have used (S)-5,5′-Bis(diphenylphosphino)-4,4′-bi-1,3-benzodioxole(cas: 210169-54-3Computed Properties of C38H28O4P2) was used in this study.
(S)-5,5′-Bis(diphenylphosphino)-4,4′-bi-1,3-benzodioxole(cas: 210169-54-3) may be used for: regio- and stereoselective preparation of axially chiral arylnaphthalene derivatives via rhodium-catalyzed [2+2+2] cycloaddition of diynes with naphthalenepropynoic acid derivatives or diastereo- and enantioselective hydrogenation of α-amino-β-keto ester hydrochlorides catalyzed by an iridium complex.Computed Properties of C38H28O4P2
