Stereoselective Synthesis of (<i>Z</i>)- and (<i>E</i>)-Allyl Aryl Sulfides and Selenides from<i>Baylis</i><i>Hillman</i>Acetates under Neutral Conditions Using<i>β</i>-Cyclodextrin in Water
The first example of the stereoselective synthesis of (Z)‐ and (E)‐allylarylsulfides and selenides from BaylisHillman acetates under neutral conditions in H2O by supramolecular catalysis involving β‐cyclodextrin is reported. β‐Cyclodextrin can be recovered and reused. The reaction is very efficient in providing allylarylsulfides and selenides in good‐to‐excellent yields with clean reaction profiles
