An efficient catalyticsystem to oxidize quantitatively aliphatic diolsusing Trametes versicolor laccase and TEMPO has been developed in aqueousmedium. Oxidations have occurred in a non-stereoselective fashion but with complete regio- and/or monoselectivity, obtaining lactones with excellent purity after simple extraction. This catalyticsystem has been demonstrated to be scalable, compatible with
