  Carbon dioxide-mediated synthesis of 3(2H)-furanones from diyne alcohols

  摘要：

  A novel type of carbon dioxide-mediated reaction of diyne alcohols without any metal catalysts was reported. Carbon dioxide held the key to the success of this reaction, in which 3(2H)-furanones were selectively obtained in moderate to high yields. (C) 2011 Elsevier Ltd. All rights reserved.

  A strategy for the highly efficient synthesis of 3(2H)-furanones by hydration of diyne alcohols catalyzed by base-functionalized ionic liquids under atmospheric-pressure CO2 that was developed through computer-assisted design is reported. The best range of basic ionic liquids as catalysts was predicted at first, and [HDBU][BenIm] exhibited the highest catalytic activity. Through a combination of NMR
