Asymmetric α‐Chlorination of β‐Keto Esters Using Hypervalent Iodine‐Based Cl‐Transfer Reagents in Combination with Cinchona Alkaloid Catalysts
We herein report an unprecedented strategy for the asymmetric α‐chlorination of β‐keto esters with hypervalent iodine‐based Cl‐transfer reagents using simple Cinchona alkaloid catalysts. Our investigations support an α‐chlorination mechanism where the Cinchona species serves as a nucleophilic cataly...
