Procedure
The above cyclopropyl aldehyde 10 (520 mg, 2.4 mmol) and 3-ethoxycarbonyl-2-methylprop-2-enylphosphonate (2.53 g, 9.6 mmol) were condensed as described for Example 1 to give 712 mg of ethyl-6-[1-(3,4-diethylbenzene)-cyclopropyl]-3-methyl-2,4-hexadienoate (11) as a pale yellow oil in 91% yield.
