英文摘要: Abstract(#br)We described herein the use of sonochemistry in the organocatalytic enamine-azide [3+2] cycloadditions of β -oxo-amides with a range of substituted aryl azides. These sonochemical promoted reactions were found to be amenable to a range of β-oxo amides or aryl azides, providing an efficient access to new N -aryl-1,2,3-triazoyl carboxamides in good to excellent yields and short times of reaction.
