✦ Synopsis

The enantioselective epoxidation of ot,~-un~turated ketones utilising Cinchona alkaloidderived quaternary ammonium phase-transfer catalysts bearing an N-anthracenylmethyl function are presented. It has been found that the O-benzyl derivatives of these catalysts in conjunction with sodium hypochlorite give high stereocontrol and application of this process to the enantioselective synthesis of a range of trans-~-epoxy ketones (e.e. 69-89%) is presented.
