α,β-Unsaturated enones possessing an unactivated olefin at the ϵ-, ζ- or η-position underwent an aluminum chloride-promoted Conia-ene-related cyclization, affording unsaturated decalones or hexahydroindenones in generally good yields. Cyclopropanes could be used as olefin surrogates in this process, leading to the same bicyclic products in slightly improved efficiency as the result of 1,2- or 1,3-hydroalkenylation
