  General Method for the Preparation of Active Esters by Palladium-Catalyzed Alkoxycarbonylation of Aryl Bromides

  摘要：

  A useful method was developed for the synthesis of active esters by palladium-catalyzed alkoxycarbonylation of (hetero)aromatic bromides. The protocol was general for a range of oxygen nucleophiles including N-hydroxysuccinimide (NHS), pentafluorophenol (PFP), hexafluoroisopropyl alcohol (HFP), 4-nitrophenol, and N-hydroxyphthalimide. A high functional group tolerance was displayed, and several active esters were prepared with good to excellent isolated yields. The protocol was extended to access an important synthetic precursor to the HIV-protease inhibitor, saquinavir, by formation of an NHS ester followed by acyl substitution.

  钯催化烯烃间碳氢键的羰基化反应

  摘要：

  我们报道了钯与酯亲电试剂和四芳基硼酸酯亲核试剂对烯烃的分子间碳酰化反应。双环烯烃与多种五氟苯甲酸苯酯和链烷酸酯和四芳基硼酸钠反应，以≤99％的产率形成酮产物。这些反应在没有引导基团的情况下发生，证明酯是分子间烯烃碳酰化反应的有效酰基亲电体。

  We report palladium-catalyzed intermolecular carboacylation of alkenes with ester electrophiles and tetraarylborate nucleophiles. Bicyclic alkenes react with a variety of pentafluorophenyl benzoate and alkanoate esters and sodium tetraarylborates to form ketone products in ≤99% yields. These reactions occur in the absence of a directing group and demonstrate esters are competent acyl electrophiles
