Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 503538-69-0, is researched, SMILESS is FC1(F)OC2=CC=C(P(C3=CC=CC=C3)C4=CC=CC=C4)C(C5=C6OC(F)(F)OC6=CC=C5P(C7=CC=CC=C7)C8=CC=CC=C8)=C2O1, Molecular C38H24F4O4P2Journal, Article, Angewandte Chemie, International Edition called Asymmetric Rhodium-Catalyzed Addition of Thiols to Allenes: Synthesis of Branched Allylic Thioethers and Sulfones, Author is Pritzius, Adrian B.; Breit, Bernhard, the main research direction is allylic thioether regioselective preparation reaction mechanism; sulfone allylic regioselective preparation; thiol allene asym addition rhodium catalyst; asymmetric catalysis; enantioselectivity; ethers; rhodium; sulfur.Reference of (R)-5,5′-Bis(diphenylphosphino)-2,2,2′,2′-tetrafluoro-4,4′-bi-1,3-benzodioxole.
A highly regio- and enantioselective hydrothiolation of terminal allenes, a reaction which fulfills the criteria of atom economy, is reported. Applying two chiral rhodium catalyst systems, a wide variety of thiols and allenes could be coupled. Oxidation gave access to the corresponding allylic sulfones in essentially enantiomerically pure form. The reaction tolerates a variety of functional groups and labeling experiments gave first insights into the reaction mechanism of this new methodol.
