Palladium-Catalyzed Decarboxylative N-3-ortho-C-H Acylation of 1,4-Disubstituted 1,2,3-Triazoles with alpha-Oxocarboxylic Acids

摘要

An efficient palladium-catalyzed decarboxylative selective C-H acylation is reported using -oxocarboxylic acids as the acyl source directed by 1,2,3-triazole ring. This method provides a novel access to various 1,2,3-triazole derivatives bearing diaryl ketone skeleton.
