Versuchsvorschrift
A mixture of the hydroxymethyloxazinone (h) (584 mg), manganese dioxide (2.3 g), THF (50 ml) and 1,2-dichloroethane (50 ml) was heated at 60° C. under argon for 20 hours. Filtration through kieselguhr and evaporation of solvent gave a solid which was triturated under EtOAc/hexane 1:3, filtered off and dried (383 mg).
