(2-氧代-1,3-二氧戊环-4-基)甲基 丙-2-烯酸乙酯

反应条件: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Following a similar preparation as described by D'Alelio and Huemmer (J. Poly. Sci., 5, 1967, pp. 307-321), to a two liter, three necked, round bottomed flask equipped with a paddle stirrer and thermometer, was added 87 g (0.74 mol.) of glycerol carbonate, followed by 1000 ml of benzene, 100 ml dioxane and 0.95 g of BHT. A drying tube and a nitrogen line were attached to the flask. Stirring was begun and the heterogeneous mixture was cooled to 0° C. with a brine bath. Two addition funnels were charged as follows: to the first was added 75 g (0.74 mol.) of triethylamine; to the second was added a solution of 100 ml of benzene and 60 g (0.66 mol.) of acryloyl chloride. Two drops of acryloyl chloride solution were added for every one drop of triethylamine. The addition took place over a period of two hours. The reaction contents were filtered through diatomaceous earth filtering media and the solution was washed with cold 5% HCl, followed by four 200 ml portions of water. 0.3 g of tert-butanol was added and the solution was dried over MgSO4. The solution was filtered to remove the drying agent and allowed to stand over a mixture of NaHCO3 and Na2SO4 for two days. The solution was filtered, transferred to a one liter, round bottomed flask and placed on a rotoevaporator. Without heat being applied, a vacuum of approximately 5 mmHg (667 Pa) was applied and the solvent was removed as completely as possible. 52 g (42%) of a light yellow liquid was recovered. 13C NMR identified the liquid to contain 86%, by weight, of the desired compound, the balance being benzene and dioxane. a similar preparation 307-321), to a two liter, three necked, round bottomed flask equipped with a paddle stirrer A drying tube and a nitrogen line were attached to the flask Two addition funnels were charged The addition of two hours The reaction contents were filtered through diatomaceous earth filtering media the solution was washed with cold 5% HCl 0.3 g of tert-butanol was added the solution was dried over MgSO4 The solution was filtered to remove the drying agent to stand over a mixture of NaHCO3 and Na2SO4 for two days The solution was filtered Without heat the solvent was removed as completely as possible 52 g (42%) of a light yellow liquid was recovered
