Tandem Addition-Cycloaddition Reaction of Oximes with 2,3-Bis(phenylsulfonyl)-1,3-butadiene as a Method for 4-Piperidone Synthesis

The reaction of oximes with 2,3-bis(phenylsulfonyl)-1,3-butadiene affords 7-oxa-1-azanorbornanes in high yield.The formation of the bicyclic isoxazolidine involves conjugate addition of the oxime onto the diene to give a transient nitrone that ten undergo
