Addition/elimination reactions of ethylsulfonyl pyridines: Stereoselective synthesis of vinylpyridine allylic alcohols
2-(Phenylsulfonyl)ethyl pyridines can be coupled with aldehydes leading directly to sulfone-eliminated vinylpyridine allylic alcohols. These products are obtained in good yield and with high levels of stereocontrol.
