Stereospecific Synthesis of Dienones via a Torquoselective Retro-Nazarov Reaction
摘要:
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.
