Studies on the Addition of Allyl Oxides to Sulfonylallenes. Preparation of Highly Substituted Allyl Vinyl Ethers for Carbanionic Claisen Rearrangements

Thirty-five allyl vinyl ethers bearing an arylsulfonyl anion-stabilizing group have been prepared by addition of allylic alkoxides to (arylsulfonyl)allenes.The allyl vinyl ethers are produced as either β,γ-unsaturated or α,β-unsaturated sulfones depending upon the substitution pattern of the allene and the reaction conditions.A wide variety of substitution patterns are available by using this method.Factors that control the position and stereochemistry of the vinyl ether double bond are discussed.

Carbanion-Accelerated Claisen Rearrangements. 2. Studies on Internal Asymmetric Induction

The stereochemical course of Claisen rearrangements of 2 and 3 in the thermal and anionic modes has been studied.The carbanionic processes were shown to be highly stereoselective and dependent upon solent, counterion, and temperature.
