The first example of Cu(ii)-mediated oxidative coupling of aromatic carboxylic acids with the C(sp3)–H bond adjacent to the keto group ofN,N-dialkylamides has been developed.

aryl esters of acetylsalicylic acid (aspirin) were synthesized and evaluated as potential prodrug forms of aspirin. N,N-Disubstituted glycolamide esters were found to be rapidly hydrolyzed in human plasma, resulting in the formation of aspirin as well as the corresponding salicylate esters. These in turn hydrolyzed rapidly to salicylic acid. The largest amount of aspirin formed from the esters were
