title: Chemoselective esterification and amidation of carboxylic acids with imidazole carbamates and ureas.
abstract: Imidazole carbamates and ureas were found to be chemoselective esterification and amidation reagents. A wide variety of carboxylic acids were converted to their ester or amide analogues by a simple synthetic procedure in high yields.
