title: Stereospecific synthesis of dienones via a torquoselective retro-Nazarov reaction.
abstract: [reaction: see text] Enol ethers are cleaved via a three-step sequence involving cycloaddition with dichloroketene, ring expansion with diazomethane, and a base-mediated retro-Nazarov reaction. The latter conrotatory process proceeds torquoselectively and stereospecifically in accord with theoretical predictions.
