(Chemical Equation Presented) The highly selective base-promoted cyclization of enantiopure sulfinyl dienols affords allylic sulfinyl dihydropyrans. The scope of this methodology, including the preparation of seven-membered rings, has been studied in dept

2-Sulfinyl dienols undergo an efficient base-promoted cyclization to produce sulfinyl dihydropyrans with creation of two asymmetric centers. The configurational stability of the allylic sulfoxide in most cases is noteworthy. Simple manipulations lead to a
