    Palladium-Templated Regio- and Stereoselective Cyclization of 2'-Alkenyl 2-Alkynoates and Its Synthetic Applications
    摘要:
    2'-Alkenyl 2-alkynoates undergo facile stereoselective cyclization to alpha-(haloalkylidene)-gamma-butyrolactones upon treatment with a catalytic amount of palladium complex in the presence of CuX(2) and LiX. When an alkyl group is introduced to the 1'-position of the alkenyl group, unsubstituted 2-propynoates mainly give trans-beta, gamma-disubstituted gamma-lactones, and substituted 2-propynoates afford cis-beta,gamma-disubstituted gamma-lactones. Further elaborations of the halogen atoms and the synthesis of A-factor using this method are exemplified.

  • Efficient Synthesis of α-Allylbutenolides from Allyl Ynoates via Tandem Ligand-Enabled Au(I) Catalysis and the Claisen Rearrangement

    日期:2019.11.1
    A facile construction of α-allylbutenolides from readily available allyl ynoates has been developed via tandem gold-catalyzed alkyne isomerization to allene and cycloisomerization, the Claisen rearrangement and a double bond migration. The gold catalysis is enabled by a bifunctional phosphine ligand featuring a critical remote tertiary amino group, and the reaction tolerates a range of substituents
