Versuchsvorschrift

To a solution of 850 mg of 4-hydroxy-6-phenylhexan-2-one (T. Mukaiyama et al., Chemistry Letters, 1976, 95) in 10 ml of methylene chloride were added 1 ml of acetic anhydride and 0.8 ml of pyridine under ice-cooling at 0° C, and then stirring was continued for further 1 hr at room temperature. The reaction mixture was poured into water, the methylene chloride layer was washed with water, dried over anhydrous sodium sulfate, and the solvent was evaporated to afford 1.10 g of the desired compound.
