The aerobic Cu/ABNO catalyzed oxidative coupling of alcohols and amines is highlighted in the synthesis of amide bonds in diverse drug-like molecules (ABNO=9-azabicyclo[3.3.1]nonane N-oxyl). The robust method leverages the privileged reactivity of alcohols bearing electronegative hetero- atoms (O, F, N, Cl) in the β-position. The reaction tolerates over 20 unique functional groups and is demonstrated

N-(Trifluoracetyl)succinimide, easily prepared from trifluoroacetic anhydride and succinimide forms a novel, convenient trifluoracetylating reagent. It trifluoroacetylates alcohols, phenols and amines, to generate trifluoroacetate esters, and trifluoracetamides in excellent yields with very efficient work up procedures.
