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.
我们在本文中描述了声化学在β-氧代酰胺与一系列取代的芳基叠氮化物的有机催化烯胺-叠氮化物[3 + 2]环加成中的用途。发现这些声化学促进的反应适合一系列β-氧代酰胺或芳基叠氮化物,从而以良好至优异的产率和短的反应时间有效地获得新的N-芳基-1,2,3-三唑基甲酰胺。
