Sonochemistry in organocatalytic enamine-azide [3+2] cycloadditions: A rapid alternative for the synthesis of 1,2,3-triazoyl carboxamides

We described herein the use of sonochemistry in the organocatalytic enamine-azide [3+2] cycloadditions of beta-oxo-amides with a range of substituted aryl azides. These sonochemical promoted reactions were found to be amenable to a range of beta-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.
