It was found that (E)-vinylic sulfones preferentially afford (Z)-allylic sulfones as kinetically-controlled products by treatment with a base under mild conditions, while (Z)-vinylic sulfones give (E)-allylic sulfones.Such stereochemical relationship was

The relative degree of "syn-effect" for the γ-substituted vinylsulfones in their conversion to the corresponding allylsulfones with 1,8-diazabicycloundec-7-ene (DBU) was determined by observing E/Z ratios of the resulting allylsulfones as follows:
