実験手順: To a solution of 1-[(methanesulfonyl)-oxy]-3,6,9-trioxadecane (11.6 g, 47.9 mmol) in dry DMF (145 ml) was added 3-iodophenol (10.6 g, 48.2 mmol) and potassium carbonate (6.6 g, 47.8 mmol). The reaction was immersed in an oil bath which was warmed to 68° C. over a period of 0.5 hr. The reaction was stirred at this temperature under an N2 atmosphere for 16 hrs and then at 82° C. for an additional 2 hrs. At the end of this period, the reaction was cooled, diluted with DMF, filtered through a pad of celite and evaporated in vacuo. The resulting residue was taken up into ethyl acetate (500 ml), washed with water (200 ml), 1N aqueous sodium hydroxide (200 ml) and brine (200 ml), dried (Na2SO4), filtered and evaporated in vacuo to provide a light brown oil. Flash column chromatography (silica, 1:3 to 1:2; EtOAc:hexane) provided 1 -(3-iodophenoxy)-3,6,9-trioxadecane as a light yellow oil (10.8 g, 37.1%). The reaction was immersed in an oil bath at 82° C. for an additional 2 hrs At the end of this period, the reaction was cooled filtered through a pad of celite evaporated in vacuo washed with water (200 ml), 1N aqueous sodium hydroxide (200 ml) and brine (200 ml) dried (Na2SO4) filtered evaporated in vacuo to provide a light brown oil

実験手順: A solution of non-polydispersed triethylene glycol monomethyl ether molecules (4.00 mL, 4.19 g, 25.5 mmol) and triethylamine (4.26 mL, 3.09 g, 30.6 mmol) in dry dichloromethane (50 mL) was chilled in an ice bath and place under a nitrogen atmosphere. A solution of methanesulfonyl chloride (2.37 mL, 3.51 g, 30.6 mmol) in dry dichloromethane (20 mL) was added dropwise from an addition funnel. Ten minutes after the completion of the chloride addition, the reaction mixture was removed from the ice bath and allowed to come to room temperature. The mixture was stirred for an additional hour, at which time TLC (CHCl3 with 15% MeOH as the elutant) showed no remaining triethylene glycol monomethyl ether. the reaction mixture was removed from the ice bath to come to room temperature
