The bicyclo[3.2.l]octane ring system is assembled by a three-step process featuring a thermally induced [4+2] cycloaddition followed by a 1,3benzodithiolium ion mediated cyclization onto an enol or silyl enol ether double bond. The bicyclo[3.2.l]octane carbon skeleton is a common structural subunit
