Strategy for the enantioselective synthesis of trans-2,4-disubstituted piperidines: Application to the CCR3 antagonist IS811

A strategy for the enantioselective synthesis of trans-2,4-disubstituted piperidines is proposed and applied to the preparation of IS811, a potent CCR3 antagonist. The C2 stereocenter is derived from commercial (R)-epichlorohydrin, while the C4 stereocent
