摘要

A simple and rapid process has been developed for the α-monohalogenation of 1, 3-keto- esters with N-halosuccinimides catalyzed by Amberlyst-15® at room temperature to produce the corresponding 2-halo 1, 3-keto-esters in high yields. This protocol also extended to α- halogenation of cyclic ketones.
