3‐(Phenylthio)‐3‐sulfolene (1) underwent spirodialkylation to give products 2 which were desulfonylated to afford the dienes 3. The Diels‐Alder reaction of 3 was achieved for some reactive dienophiles to yield spiro compounds. Compounds 2 were also converted to sulfonyldienes 9 which reacted as Michael acceptors.
