Abstract A dynamic kinetic resolution process was applied to an enantioconvergent microbial Baeyer–Villiger oxidation of benzyloxycyclopentanone, rac-1. This was achieved by combining a whole cell-based kinetic resolution and an anion exchange resin-catalysed in situ racemisation. Several resins were screened according to their capacity to catalyse the racemisation of 1. As compared to our previous results, the presence of weakly basic ...
