A copper-catalyzed direct C-H acyloxylation of [2.2]paracyclophanes utilizing an oxazoline amide directing group has been developed. A range of carboxylic acid substrates, including aromatic, alkenyl, and alkyl carboxylic acids, are tolerated, delivering the corresponding acyloxylated products in moderate to good yields. Gram-scale reactions and subsequent hydrolysis experiments further demonstrate the synthetic utility of this method. This work provides an efficient and convenient strategy for the selective functionalization of [2.2]paracyclophanes, highlighting its potential for practical applications.

Key words: Copper catalysis, Amide oxazoline directed, C-H acyloxylation, [2.2]Paracyclophanes
