  Alkynyltrifluoroborates as Versatile Tools in Organic Synthesis:  A New Route to Spiroketals

  摘要：

  A simple and efficient two-step approach to spiroketals is described. Key steps include the preparation of functionalized hydroxyl alpha-alkynones by ring-opening reactions of lactones with lithium alkynyltrifluoroborates followed by a palladium-catalyzed hydrogenation/spirocyclization of the prespiroketal intermediate.
