Sulfone, chloromethyl phenyl epoxidation

Reactions of carbonyl compounds and imines. The salt 4 obtained from reaction of cinchonine with m-xylylene dibromide is shown to promote enantioselective transfer of the trifluoromethyl group from Me3SiCF3 to aryl ketones Also obtained from quinidine the salt containing a trifluorobenzyl group (5) promotes the condensation of chloromethyl phenyl sulfones with ArCFlO to give benzenesulfonyl epoxides ...
