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.

Ring Opening Of Epoxides

Silica-bonded S-sulfonic acid (SBSSA) was used as a recyclable and reusable catalyst for the synthesis of β-amino alcohols. Several amines were reacted with epoxides to afford regioselective β-amino alcohols in high yield under solvent-free conditions at room temperature.
