MgO catalyzed efficiently the ring opening of epoxides with a range of aromatic and aliphatic amines to produce β-substituted alcohols in high yields under solvent-free conditions. Exclusive trans stereoselectivity is observed for cyclic epoxide.Key words: MgO, β-amino alcohols, solvent-free, epoxide, amine.
