Carbanion-Accelerated Claisen Rearrangements. 6. Preparative and Stereochemical Studies with Sulfonyl-Stabilized Anions

The aliphatic Claisen rearrangement is markedly accelerated by an arylsulfonylmethide substituent at position 2.The generality of this anion variant has been extensively examined (31 allyl vinyl ethers) with regard to substitution, stereochemistry, and an

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.
