In the manner of Example 12A, the reaction of 1.5 g (0.007 mole) of (+)-4-phenyl-2-indanol (EE≥95%) and 1.77 g (0.007 mole) of (+)-cis-3-(2-chloro-3,3,3-trifluoro-1-propenyl)-2,2-dimethylcyclopropanecarbonyl chloride in the presence of 0.7 g (0.009 mole) of pyridine and 20 ml of toluene gave 1.87 g of (+)-4-phenyl-2-indanyl (+)-cis-3-(2-chloro-3,3,3-trifluoro-1-propenyl)-2,2-dimethylcyclopropanecarboxylate as an oil, EE≥95% (alcohol moiety). The nmr spectrum was consistent with the proposed structure.
