Reaction Steps

In a manner similar to Example 12A, the reaction of 0.41 g (0.0018 mole) of (±)-trans-3-(2,2-dichloroethenyl)-2,2-dimethylcyclopropanecarbonyl chloride with 0.37 g (0.0018 mole) of (+)-4-phenyl-2-indanol (EE 50%), 0.16 g (0.002 mole) of pyridine and toluene gave (+)-4-phenyl-2-indanyl (±)-trans-3-(2,2-dichloroethenyl)-2,2-dimethylcyclopropanecarboxylate, EE 50% (alcohol moiety). The nmr and ir spectra were consistent with the proposed structure.
