• Gold-Catalyzed Tandem Oxidative Coupling Reaction between β-Ketoallenes and Electron-Rich Arenes to 2-Furylmethylarenes

  日期：2021.8.6

  A tandem oxidative coupling reaction of β-ketoallenes and arenes was developed, which leads to the formation of 2-furylmethylarenes using AuCl3 and phenyliodine diacetate. The AuIII salt catalyzed the cyclization of β-ketoallenes to form a 2-furylmethyl gold intermediate, and the subsequent C–H functionalization of arenes proceeded smoothly. During the oxidative coupling, nucleophilic additions occurred

  日期：1996.8

  A new lactone synthesis was developed using the Fischer chromium carbene complex. The lactone was formed from an alkyne bearing a hydroxyl or silyloxyl group in a tether, along with carbene carbon and carbon monoxide of the chromium carbene complex. Using this procedure, (+)-blastmycinone and (+)-antimycinone were synthesized from (S)-ethyl lactate in short steps.

  A series of alkynyl ethers react with an electrophilic gold(I) catalyst to produce a range of structurally complex spiro or fused dihydrofurans and dihydropyrans via a 1,5-hydride shift/cyclization sequence. This hydroalkylation process, which is performed under practical experimental conditions, can be applied to terminal as well as ester-substituted alkynes. It allows the efficient conversion of
