Notes:
2,4-Dioxopentane-3-thione 1a reacts as an enophile with various allyl derivatives affording thiophilic ene adducts as single regioisomers with high (E) stereoselectivity. Using allyl ethers or allenes as ene counterparts, the formation of the thiophilic adduct is followed by a fast cycloaddition reaction in which 1a behaves as a diene or a dienophile, respectively.
