The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: (11bR)-N,N-Bis[(1R)-1-phenylethyl]dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-amine(SMILESS: C[C@@H](N(P1OC2=CC=C3C=CC=CC3=C2C4=C5C=CC=CC5=CC=C4O1)[C@@H](C6=CC=CC=C6)C)C7=CC=CC=C7,cas:415918-91-1) is researched.Synthetic Route of C17H19N3O2S. The article 《Stereodivergent Synthesis of Enantioenriched γ-Butyrolactones Bearing Two Vicinal Stereocenters Enabled by Synergistic Copper and Iridium Catalysis》 in relation to this compound, is published in Angewandte Chemie, International Edition. Let’s take a look at the latest research on this compound (cas:415918-91-1).
By virtue of a fundamentally new reaction model of azomethine ylide serving as a two-atom synthon, the first example of stereodivergent preparation of [(3R,4S)/(3S,4R)/(3R,4R)/(3S,4S)]-γ-butyrolactones I (R = Me, benzyl, allyl, 2-ethoxycarbonylethyl, etc.) via synergistic Cu/Ir-catalyzed asym. cascade allylation/lactonization is presented, and all four stereoisomers of I bearing two vicinal stereocenters are accessible with excellent diastereoselective and enantioselective control. The chiral IrIII- π-allyl intermediate was separated and characterized to understand the origin of the regio- and stereoselectivity of the initial C-C bond formation process. Control experiments shed some light on the catalyst/substrate and catalyst/catalyst interactions in this dual catalytic system to rationalize the related kinetic/dynamic kinetic resolution process with different catalyst combinations. The enantioenriched γ-butyrolactone products I were converted into an array of structurally complex chiral mols. and organocatalysts that were otherwise inaccessible.
