enantioselective synthesis of bothenantiomers of bepridil, a calcium channel blocker, is reported. Jacobsen's hydrolytic kinetic resolution method was utilized to resolve racemic 2-(isobutoxymethyl)oxirane. The incorporation of the succinimide moiety by the Mitsunobu reaction, which was investigated in detail, occurred without any loss of enantioselectivity. Using this strategy, bothenantiomers of the target
