We report mixed carbonates as enzyme substrates and demonstrate their application as fluorogenic probes for lipase and esterase enantiopreference screening. By the application of pseudoenantiomers with distinct fluorescence behaviors, it is possible to evaluate the activity and enantiopreference of hydrolytic enzymes. In order to validate our method, enantioselectivities calculated from fluorometric measurements were compared with the results obtained from larger-scale kinetic resolution.
