実験手順: To a solution of 17-azido-3,6,9,12,15-pentaoxaheptadecanamine (15 g, 50 mmol) in dichloromethane (100 mL) was added diglycolic anhydride (Acros, 6.4 g, 55 mmol). The reaction mixture was stirred overnight. The reaction was monitored by ESI-MS analysis, and more reagents were added to drive the reaction to completion. The solution was concentrated to give a yellow residue which was dissolved in water (250 mL). The product was isolated from the aqueous phase by continuous extraction with dichloromethane over night. Drying and evaporation of the solvent gave a yield of 18 g (85%). The product was characterized by ESI-MS analysis (MH+ calculated: 423.20; found 423.4). The product was used in the next step without further purification. were added the reaction to completion The solution was concentrated to give a yellow residue which Drying evaporation of the solvent gave a yield of 18 g (85%) The product was used in the next step without further purification

実験手順: To a vigorously stirred suspension of 1,17-diazido-3,6,9,12,15-pentaoxaheptadecane (25 g, 75 mmol) in 5% HCl (200 mL) was added a solution of triphenylphosphine (19.2 g, 73 mmol) in ether (150 mL) over 3 hrs at room temperature. The reaction mixture was stirred for additional 24 hrs. The phases were separated and the aqueous phase was extracted with dichloromethane (3×40 mL). The aqueous phase was cooled in an ice/water bath and the pH was adjusted to 12 by addition of solid potassium hydroxide. The aqueous phase was concentrated and the product was taken up in dichloromethane (150 mL). The organic phase was dried (Na2SO4) and concentrated giving of 22 g (95%) of a yellow oil. The product was identified by electrospray mass spectrometry (ESI-MS) (MH+ calculated: 307.19; found 307.4). The crude oil was used in the nest step without further purification. The phases were separated the aqueous phase was extracted with dichloromethane (3×40 mL) The aqueous phase was cooled in an ice/water bath the pH was adjusted to 12 by addition of solid potassium hydroxide The aqueous phase was concentrated The organic phase was dried (Na2SO4) concentrated
