Regio- and stereo-selective γ-substitution of allylic sulphoxides and sulphones with lithium dialkylcuprates. A new synthesis of trisubstituted olefins
Abstract
A new regio- and stereo-selective γ-substitution of allylic sulphoxides and sulphones with lithium dialkylcuprates providing a promising new method for the preparation of trisubstituted olefins in particular is described.
