- Palladium-catalyzed C-H bond carboxylation of acetanilides: An efficient usage of N,N-dimethyloxamic acid as the carboxylate source
-
N,N-Dimethyloxamic acid can be successfully employed as a carboxylate precursor in the palladium-catalyzed direct C-H carboxylation of acetanilides. The reaction proceeds smoothly under mild conditions over a broad range of substrates with high functional group tolerance, affording substituted N-acyl anthranilic acids in moderate to high yields.
