Abstract Lipases and esterases can be used to fragment the 4-acetyloxybenzyloxy group used as a linker for organic synthesis on solid supports.(A support-bound compound is shown on the right; the enzyme-labile bond is marked with an arrow.) This enzyme-initiated fragmentation proceeds under very mild conditions (pH 6–7, room temperature), and the compounds of interest (amines, alcohols, carboxylic acids; X= NH, O, CR 2) constructed ...
