The dienophilic reactivity of allenes is drastically increased by the powerful electron withdrawing trichloromethylsulfonyl or sulfinyl substituents. The [4+2]-cycloadditions proceed smoothly with high regio- and stereoselectivity under mild conditions. Using an optically active allenyl sulfone, transfer of chirality has been observed.
