An efficient TfOH-catalyzed O—H insertion reaction of α-aryl diazoesters with carboxylic acids is reported. This metal-free protocol provides an operationally simple method for a one-pot assembly of diverse α-acyloxy esters in moderate to high yields with a broad substrate scope. All starting materials are readily available, and the reactions can be conducted in the open air at room temperature.

Key words: carboxylic acids, α-aryl diazoesters, TfOH, O—H insertion
