The base-mediated reaction of α,β-unsaturatedcarbonylcompounds and γ-phosphonylcrotonates under an argon atmosphere readily furnishes substituted cyclohexa-1,3-dienes. The cyclisation proceeds with complete regioselectivity to afford products that are readily amenable to further redox manipulations. The presented method allows the rapid and regioselective syntheses of six-membered carbocycles at
