Ethynyl-cyclohexanol: an efficient acetylene surrogate in Sonogashira coupling
摘要:
The Sonogashira coupling of aryl halides in the presence of 1-ethynyl-cyclohexanol as an acetylene source provides an efficient method for the synthesis of diarylacetylenes without the isolation of the appropriate arylacetylenes. (c) 2007 Elsevier Ltd. All rights reserved.

Carbon Dioxide Triggered and Copper-Catalyzed Domino Reaction: Efficient Construction of Highly Substituted 3(2<i>H</i>)-Furanones from Nitriles and Propargylic Alcohols
A novel carbon dioxide triggered and copper-catalyzed domino reaction for the efficient synthesis of highlysubstituted 3(2H)-furanones from readily available nitriles and propargylic alcohols has been developed. Carbon dioxide is a prerequisite for achieving the present catalytic transformation, and one of the oxygen atoms of carbon dioxide is incorporated into the 3(2H)-furanones. Nitriles not only
