2-coumaryloxy ketones using meta-chloroperbenzoic acid proceeded regioselectively to the corresponding acyloxyalkyl derivatives of umbelliferone and nitrophenol. These chiral lactones underwent a fluorogenic and chromogenic reaction upon hydrolysis by esterases, in particular pig liver esterase. Enantioselectivity of the ester hydrolysis reaction was determined by chiral-phase analysis of the unreacted lactones
