A broad range of highly enantioenriched 2-acylimidazoles are synthesized by palladium-catalyzed decarboxylative asymmetricallylicalkylation (DAAA) of 2-imidazolo-substituted enol carbonates. The enantioenriched 2-acylimidazole products can easily be converted to the corresponding carboxylic acid, ester, amide, and ketone derivatives with complete retention of the enantiopurity. The synthetic utility
