实验步骤: To a solution of tetrahydrofuran (140 mL) containing sodium hydride (0.43 g, 18 mmol) was added dropwise a solution of monodispersed tetraethylene glycol (3.5 g, 18 mmol) in tetrahydrofuran (10 mL) and the reaction mixture was stirred for 1 h. Then mesylate of monodispersed tetraethylene glycol monobenzylether 24 (6.0 g, 16.5 mmol) dissolved in tetrahydrofuran (10 mL) was added dropwise and the reaction mixture was stirred overnight. The crude reaction mixture was filtered through Celite (washed; CH2Cl2, 250 mL) and the filtrate was washed H2O, dried MgSO4, and evaporated to dryness. The resultant oil was chromatographed (silica, ethyl acetate/methanol, 10:1) and chromatographed (silica, chloroform/methanol, 25:1) to afford the monodispersed compound 25 as a clear oil (2.62 g, 34% yield). was added dropwise the reaction mixture was stirred overnight The crude reaction mixture was filtered through Celite (washed; CH2Cl2, 250 mL) the filtrate was washed H2O, dried MgSO4 evaporated to dryness The resultant oil was chromatographed (silica, ethyl acetate/methanol, 10:1) chromatographed (silica, chloroform/methanol, 25:1)

实验步骤: To the oil of monodispersed tetraethylene glycol (19.4 g, 0.10 mol) was added a solution of NaOH (4.0 g in 4.0 mL) and the reaction was stirred for 15 mm. Then benzyl chloride (3.54 mL, 30.8 mmol) was added and the reaction mixture was heated to 100° C. and stirred overnight. The reaction mixture was cooled to room temperature, diluted with sat. NaCl (250 mL), and washed CH2Cl2 (2×200 mL). The organic layers were combined, washed sat. NaCl, dried MgSO4, and chromatographed (silica, ethyl acetate) to afford the monodispersed compound 23 as a yellow oil (6.21 g, 71% yield). stirred overnight The reaction mixture was cooled to room temperature washed CH2Cl2 (2×200 mL) washed sat. NaCl, dried MgSO4 chromatographed (silica, ethyl acetate)
