Participants

Reaction Steps

(RS)-3-ethyl-3-cyclopenten-1-ol (500 mg) and (1R)-cis-2,2-dimethyl-3-(2,2-dichlorovinyl)cyclopropanecarbonyl chloride (1014 mg) were respectively used instead of (RS)-3-ethyl-4-methyl-3-cyclopenten-1-ol and (1RS)-cis-3-(Z-2-chloro-3,3,3-trifluoro-1-propenyl)-2,2-dimethylcyclopropanecarbonyl chloride used in Example 1 above and the reaction procedures were carried out in the same manner as in Example 1 to afford 1150 mg of (RS)-3-ethyl-3-cyclopentenyl (1R)-cis-2,2-dimethyl-3-(2,2-dichlorovinyl)cyclopropanecarboxylate (Compound No. 132).
