实验步骤: A 1000 mL three necked round bottomed flask outfitted with a mechanical stirrer (Teflon paddle), a pressure equalizing addition funnel was charged with pentaerythritol triallyl ether (NEOALLYL P-30) (111.9 g, 436.5 mmol), toluene (300 mL) and triethylamine (56.61 g, 559.4 mmol). The addition funnel was charged with a solution of BCB-AA acid chloride (88.96 g, 461.8 mmol) from Example 6 in toluene (100 mL), which was then added dropwise to the reaction mixture over 45 min. The solution was then heated to 90° C. for 9.5 hr. The solution was then filtered through a 38 mm (1.5 inch) thick silica gel plug on a 350 mL fritted glass funnel. Hexane:ethyl acetate (80:20, 200 mL) was used as the washing solvent. The filtrate was condensed to afford an orange colored viscous oil, which was taken up in hexanes (300 mL) and placed into a freezer for 3 days. The solution was filtered and condensed to afford the product as a viscous dark yellow colored oil.

实验步骤: 30.7 g (0.12 mol) of pentaerythritol triallylether was dissolved in 100 ml of dry THF and 4.4 g (0.18 mol) of NaH was added in small portions while stirring. After gas evolution had ceased, 16 ml (0.18 mol) of allyl bromide was added and the reaction mixture was stirred overnight at room temperature. In order to drive the reaction to completion, it was subsequently brought to reflux and stirred for 1 hr. The precipitated salts were removed by filtration over ca. 1 cm of Celite 545 and the solvent and excess allyl bromide were evaporated, yielding 35.3 g (99.5%) of a pale yellow oil. The raw product was dissolved in 100 ml of diethyl ether and washed subsequently with 50 ml of 0.1 M aqueous KHSO4 and 50 ml of saturated aqueous NaHCO3 solution. Drying the organic layer with MgSO4 and evaporation of the solvent yielded 34.4 g (97%) of the pure product. the reaction mixture was stirred overnight at room temperature the reaction to completion, it to reflux stirred for 1 hr The precipitated salts were removed by filtration over ca. 1 cm of Celite 545 the solvent and excess allyl bromide were evaporated
