Procedure: To a THF solution of 1.53 g (13 mmol) of tert-butylcyclopentadiene, 9.0 ml (14 mmol) of a hexane solution of n-butyllithium was dropwise added in a nitrogen atmosphere with ice cooling, followed by stirring at room temperature for one night. Then, 1.7 ml (16 mmol) of 3-pentanone was further added at −78° C., followed by stirring at room temperature for 2 days. To the reaction solution, water was added. The mixture was subjected to extraction with ether, then the solvent was distilled off, and the residue was subjected to column chromatography (silica gel, developing solvent: hexane) to obtain 1.50 g of a yellow liquid (yield: 63%) The analyzed values are given below. by stirring at room temperature for 2 days The mixture was subjected to extraction with ether the solvent was distilled off

Procedure: To a mixed solution of 1.40 g (11 mmol) of tert-butylcyclopentadiene, 8.4 ml (114 mmol) of acetone and 20 ml of methanol, 9.5 ml (114 mmol) of pyrrolidine was added with ice cooling, followed by stirring at room temperature for one night. To the reaction solution, 50 ml of water, 100 ml of ether and 3 ml of acetic acid were added with ice cooling. The separated organic phase was washed with water and dried over anhydrous sodium sulfate. After the solvent was distilled off, the residue was subjected to column chromatography (silica gel, developing solvent: hexane) to obtain 1.62 g of a yellow liquid (yield: 88%) The separated organic phase was washed with water dried over anhydrous sodium sulfate After the solvent was distilled off
