Reglo-, stereo-, and facial selective [4 + 2] cycloadditions between highly activated vinyl sulfones and 1,3-dienes derived from (R)-4-tert-wbutyldimethylsilyloxy-2-cyclohexen-1-one provide a powerful approach for the asymmetric synthesis of compounds containing the bicyclo[2.2.2]octanone carbon skeleton. This new methodology has been successfully applied to the asymmetric synthesis of the cis-decalin core structure of the potent anticancer marine natural products superstolides A and B.
