The example of enantioselective kinetic resolution (KR) of racemic terminal epoxides using phthalimide as the nucleophile catalyzed by chiral salen(Co)(OAc) is described. The process afforded enantiopure epoxides and enantioenrich N-protected 1,2-amino alcohol in moderate ee value. Using an easily accessible catalyst and inexpensive staring materials, the reaction was conveniently carried out without protected atmosphere.

Key words: phthalimide, terminal epoxide, chiral salen(Co)(OAc), kinetic resolution
