实验步骤: Diethyl azodicarboxylate (0.5 g) was added dropwise over 1 minute to a stirred solution of triphenylphosphine (0.75 g) in tetrahydrofuran (20 ml) at -78° C. under a nitrogen atmosphere. The reaction mixture was stirred for 5 minutes and then 6-hepten-1-ol (0.36 g) was added dropwise over 1 minute, followed by stirring at -78° C. for a further 5 minutes. Neopentanol (0.12 g) was added to the reaction mixture, followed by 3-azabicyclo[3.1.0]hexane-2,4dione (0.32 g) and stirring was continued for a further 5 minutes at -78° C. The reaction mixture was warmed to room temperature and stirred overnight. The volatiles were removed by evaporation in vacuo and the residue was triturated with hexane/dichloromethane and then filtered. The filtrate was evaporated in vacuo and then purified by chromatography on silica gel using 20% ethyl acetate/hexane as eluant. The title compound was obtained as a colourless oil (boiling point 150-160° C. @ 1 mmHg). by stirring at -78° C. for a further 5 minutes stirring was continued for a further 5 minutes at -78° C stirred overnight The volatiles were removed by evaporation in vacuo the residue was triturated with hexane/dichloromethane filtered The filtrate was evaporated in vacuo purified by chromatography on silica gel using 20% ethyl acetate/hexane as eluant

实验步骤: This example illustrates a synthesis of 1-(6,7-Oxidoheptyl)-3,7-dimethylxanthine (inventive compound no. 1586). To a solution of 6-hepten-1-ol (6.00 g, 52.6 mmol) in dichloromethane (120 mL) at 0° C. was added methanesulfonyl chloride (6.07 g, 4.0 mL, 53.0 mmol), followed by triethylamine (7.79 g, 77.0 mmol). After stirring for 10 minutes at 0° C., the reaction was allowed to warm to 25° C. and then stirred for 2 hours.
