[1305] Under a nitrogen atmosphere, in a 300mL three-necked flask, add 3,6-di-tert-butyl-fluorene 1 5.22g (54.7 mmol) and propylene carbonate 170ml, stirring. To this solution was added 20.52 g (115 mmol) of N-bromosuccinimide, followed by heating and stirring at 80° C. for 5 hours. Then, it was naturally left to cool, and the reaction solution was added to 800 mL of water, and stirred at room temperature for 15 minutes, and the precipitated solid was separated by filtration. The obtained solid was washed 5 times with 10 mL of ethanol. Then, a mixed solution of n-hexane and a small amount of dichloromethane was added to the solid, heated to 60°C to completely dissolve, and then left to stand overnight at -20°C. The precipitated crystals were washed three times with 5 mL of hexane to ob...

[1326] Under a nitrogen atmosphere, 15 mL of methanol and 11.8 mL (146 mmol) of pyrrolidine were added to a 200 mL three-necked flask. After cooling in an ice bath, 20.21 g (144 mmol) of 5-nonanone and 11.0 mL (146 mmol) of cyclopentadiene were added, followed by stirring at room temperature for 22 hours. 100 mL of diethyl ether and 100 mL of water were added, and the soluble portion was extracted. The organic layer was washed twice with water, once with saturated brine, and dried over magnesium sulfate. The solvent was distilled off, and the residue was purified by column chromatography to obtain the target product as a yellow oil (yield: 22.53 g, yield: 82%). Identification and utilization of target products 1 H-NMR performed.
