实验步骤: 5-Iodo-2'-deoxyuridine (354 mg, 1 mmol) was dissolved in 10 mL of dimethylformamide. Cuprous iodide (76 mg, 0.4 mmol), tetrakis(triphenylphosphine)palladium(0) (230 mg, 0.2 mmol), and triethylamine (200 mg, 2.0 mmol) were added. 4-Phthalimidobut-1-yne (300 mg, 1.5 mmol) was added all at once and the reaction kept at 60° C. for three hours. The clear yellow reaction was then evaporated and methylene chloride was added. Scratching of the flask induced crystallization of nearly all of the product which was filtered and recrystallized from 95% ethanol to give 335 mg (78%) of title compound as fine, feathery needles. The clear yellow reaction was then evaporated methylene chloride was added crystallization of nearly all of the product which was filtered recrystallized from 95% ethanol

实验步骤: Diisopropyl azodicarboxylate (316 g, 1.56 mol) was added to a solution of triphenylphosphine (PPh3) (393 g, 1.50 mol), 3-butyn-1-ol (105 g, 1.50 mol) and phthalimide (200 g, 1.36 mol) in toluene (1600 mL) which was pre-cooled with a −5° C. cooling bath at such a rate that temperature of the reaction mixture was kept between 15-25° C. The addition time was 50 min. The cooling bath was removed after the addition was finished. The reaction mixture was allowed to warm to 15-25° C. and stirred for 1 h.

The filtrate is concentrated under reduced pressure to a volume of less than 6 L, and N,N-dimethylformamide (8 L) is added to the residue. The mixture is concentrated until tetrahydrofuran is removed. Piperidine (535 g, 6.29 mol) is added to the mixture. The mixture is stirred and warmed to 100° C. The mixture is maintained at 100° C. until the product/starting material ratio is >97/3. The mixture is cooled to 32° C. Water (4.2 L) is added to the stirred mixture over >100 min, allowing the temperature of the mixture to rise to 45° C. The mixture is cooled (0-5° C.).
