A protocol for the enantioselective organocatalytic chlorina- tion of cyclic and acyclic b -keto esters and cyclic b -diketones has been developed which is also effective forthe asymmetric bromination of b -keto esters.The metho- dology employs an inexpensive organo- catalyst (e.g.benzoylquinidine)and poly- halogenated quinolinones as the source of the halogen.

Abstract

A protocol for the enantioselective organocatalytic chlorina- tion of cyclic and acyclic b -keto esters and cyclic b -diketones has been developed which is also effective forthe asymmetric bromination of b -keto esters.The metho- dology employs an inexpensive organo- catalyst (e.g.benzoylquinidine)and poly- halogenated quinolinones as the source of the halogen.
