Tandem Michael−Wittig−Horner Reaction: One-Pot Synthesis of δ-Substituted α,β-Unsaturated Carboxylic Acid Derivatives − Application to a Concise Synthesis of (Z)- and (E)-Ochtoden-1-al
A new tandem Michael−Wittig−Horner reaction has been developed to produce in high yields δ-substituted α,β-unsaturated esters, amides and lactones. The reaction has been successfully applied to a concise synthesis of (E)- and (Z)-ochtoden-1-als, components of the male sex pheromone of boll weevil from 3-methylcyclohex-2-en-1-one.

direct synthesis of δ-substituted α,β-unsaturatedesters from unsubstituted al dehydes or ketones has been accomplished in high yield by a taodem 1,4-addition and Wittig-Horner reaction. The Copper-enolate obtained after the first step was able to deprotonate the highly acidic phosphonate generating thus the two components necessary for the second coupling reaction.
