Xiao, Lu;Wei, Liang;Wang, Chun-Jiang research published 《 Stereodivergent Synthesis of Enantioenriched γ-Butyrolactones Bearing Two Vicinal Stereocenters Enabled by Synergistic Copper and Iridium Catalysis》, the research content is summarized as follows. 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.
