Reaction Steps

To a mixture of (RS)-3-(2-propenyl)-4-methyl-3-cyclopenten-1-ol (190 mg), 2,6-di-tert-butyl-4-methylphenol (5 mg), pyridine (140 mg) and toluene (10 ml), (1R)-trans-2,2-dimethyl-3-(2,2-dichlorovinyl)cyclopropanecarbonyl chloride (310 mg) was added under ice-cooling. The resulting reaction mixture was further allowed to react for 8 hours at room temperature. Then the reaction mixture was subjected to the same post-treatment as in Example 1 to afford 379 mg of (RS)-3-(2-propenyl)-4-methyl-3-cyclopenten-1-yl (1R)-trans-2,2-dimethyl-3-(2,2-dichlorovinyl)cyclopropanecarboxylate (Compound No. 18).
