实验步骤: A solution of 2.00 g (10.3 mmol) 1,1-diphenylpropene and 2.09 g (10.4 mmol) 85% m-chloroperbenzoic acid in 15 ml dichloromethane was stirred in the dark at room temperature for 4 hours. The mixture was partitioned between dichloromethane and saturated K2CO3 solution and the organic layer was washed with brine and dried over Na2SO4. This was concentrated to give 2.14 g (98%) of 2,2-diphenyl-3-methyloxirane as a colorless oil. The mixture was partitioned between dichloromethane and saturated K2CO3 solution the organic layer was washed with brine dried over Na2SO4 This was concentrated

实验步骤: A mixture of 1,1-diphenyl-1-propanol (64 g, 0.30 mol), isopropanol (300 ml) and a 5 N solution of sulphuric acid (150 ml) was heated at reflux temperature for 18 h. The reaction mixture was cooled, diluted with water (600 ml) and extracted with toluene (3×150 ml). The combined organic phases was dried (Na2SO4) and the solvent was evaporated in vacuo to give a solid residue which was triturated with iso-octane. The solid was collected by filtration to give 28.8 g (49%) of 1,1-diphenyl-1-propene. at reflux temperature for 18 h The reaction mixture was cooled extracted with toluene (3×150 ml) The combined organic phases was dried (Na2SO4) the solvent was evaporated in vacuo to give a solid residue which was triturated with iso-octane The solid was collected by filtration

实验步骤: Into a reactor were introduced 19.4 g (100 mmol) of the 1,1-diphenylpropene and 78 mL of 1,2-dichloroethane under a nitrogen atmosphere. The contents were cooled to 0° C., and 15.9 g (100 mmol) of bromine was gradually added dropwise thereto. The resultant mixture was stirred at room temperature for 1 hour. Thereafter, 32.4 mL (400 mmol) of pyridine and 156 mL of toluene were added thereto and this mixture was stirred at 80° C. for 3 hours. After being cooled, the reaction mixture was washed with saturated aqueous sodium hydrogen carbonate solution and saturated aqueous sodium chloride solution and then dried with anhydrous magnesium sulfate. Thereafter, the solvent was removed under reduced pressure. The concentrate was purified by column chromatography and then recrystallized from methanol to obtain 14.5 g (53%) of the target compound as white crystals. After being cooled the reaction mixture was washed with saturated aqueous sodium hydrogen carbonate solution and saturated aqueous sodium chloride solution dried with anhydrous magnesium sulfate Thereafter, the solvent was removed under reduced pressure The concentrate was purified by column chromatography recrystallized from methanol
