Procedure

212 mg (1.60 mmol) of 1,2,3,4-tetrahydronaphthalene in 1.1 ml of acetone were reacted analogously to Example 1 with 71 mg (0.53 mmol) of 1-hydroxy-1H-benzotriazole in 3 ml of acetone and 15 ml of an aqueous solution of 2 mg/ml laccase from Trametes versicolor. After a reaction time of 24 hours, the reaction solution was extracted with chloroform and examined by NMR spectroscopy. Yield 42% of 1-tetralone and 6% of 5-hydroxytetralin (approx. 90% yield of 1-tetralone based on conversion).
