Versuchsvorschrift

4-Hydroxymethyl-5-methyl-3-phenyl-2(5H)-furanone (Compound 7), (73 mg, 0.36 mmol), lauroyl chloride (117 mg, 0.54 mmol), triethylamine (47 mg, 0.47 mmol) and dimethylaminopyridine (1 mg, 0.01 mmol) were stirred in anhydrous THF (2 mL) at ambient temperature under argon for 2 hours. The crude reaction mixture was concentrated, the organics were extracted into diethyl ether and solids were filtered off. The ether was removed by rotary evaporator and the resulting oil was purified by flash chromatography on silica to give the title compound.
