実験手順
Prostratin (1390 mg, 1 mmol) and succinic anhydride (120 mg, 1.2 mmol) were dissolved in dichloromethane (20 ml). DMAP (dimethylaminopyridine) at 50 mg was added under stirring and then stirred at room temperature for overnight. The solvent was evaporated and the residue subjected to chromatography on silica gel column (50 mg) with gradient of petroleum ether (60-90° C.) and acetone as eluent to give a fraction of pure prostratin succinate (Scheme (1), product 1) and another fraction containing a mixture of prostratin and prostratin succinate.
