实验步骤: 1-(8,9-Oxidononyl)-3,7-dimethylxanthine was synthesized as follows: A mixture of theobromine (17.64 g, 98 mmol) and sodium hydride (2.35 g, 98 mmol) in dimethylsulfoxide (250 ml) was stirred for 15 minutes. 9-Bromo-1-nonene (20.0 g, 98 mmol) was added and stirring continued for 3 days. The reaction mixture was poured into water (300 ml) and extracted with dichloromethane (4×200 ml). The combined organic layers were washed with saturated aqueous sodium chloride solution (2×150 ml), dried over sodium sulfate, and the solvents evaporated under vacuum. The residue was crystallized (dichloromethane-ether) to give 1-(8-nonenyl)-3,7-dimethylxanthine (24.34 g, 99% yield) as white crystals. stirring continued for 3 days extracted with dichloromethane (4×200 ml) The combined organic layers were washed with saturated aqueous sodium chloride solution (2×150 ml) dried over sodium sulfate the solvents evaporated under vacuum The residue was crystallized (dichloromethane-ether)

实验步骤: This example illustrates a synthesis of 1-Methyl-3-(8,9-oxidononyl)thymine (inventive compound no. 1910). Sodium hydride (343 mg, 14 mmol) was added to a stirring solution of 1-methylthymine (2.00 g, 14 nmuol) in dimethylsulfoxide (40 mL). After 15 minutes, 9-bromo-1-nonene (2.93 g, 14 mmol) was added and the mixture stirred for 20 hours. The reaction was poured into 40 mL water and extracted with dichloromethane (3×50 mL). The organic layers were combined, washed with water (40 mL), saturated aqueous salt solution (20 mL), and dried over sodium sulfate. The solvent was evaporated to yield 2.76 g (73% yield) 1-Methyl-3-(8-nonenyl)thymine (inventive compound no. 1917) as a colorless oil which solidified upon standing. extracted with dichloromethane (3×50 mL) washed with water (40 mL), saturated aqueous salt solution (20 mL) dried over sodium sulfate The solvent was evaporated

实验步骤: This example illustrates a synthesis of N-(9,8-Oxidononyl)phthalimide (inventive compound no. 1105). 1-bromo-8-nonene (8.2 g, 40 mmol) was added to a suspension of potassium phthalimide (7.4 g, 40 mmol) in 50 mL of dimethyl sulfoxide and stirred overnight. After 12 hours of stirring at room temperature, the reaction product was poured into a separatory funnel containing 300 mL of water and extracted with dichloromethane (5×200 mL). Organic extracts were combined, washed with water (100 mL) and brine (100 mL), dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The crude product obtained was further purified by flash chromatography over silica gel (using an eluant of 10% acetone/hexane) to yield 7.6 g (70.4% yield) of N-(8-Nonenyl)phthalimide (inventive compound no. 1101). After 12 hours of stirring at room temperature the reaction product was poured into a separatory funnel extracted with dichloromethane (5×200 mL) washed with water (100 mL) and brine (100 mL) dried over anhydrous magnesium sulfate concentrated under reduced pressure The crude product obtained was further purified by flash chromatography over silica gel (
