Lithium perchlorate catalyzed the ring opening of epoxides with amines to provide the corresponding β-aminoalcohols in excellent yields with high regioselectivity. The reaction proceeds rapidly under mild and neutral conditions and worked well with primary, secondary, aliphatic, aromatic, and hindered amines in short times at room temperature, in the absence of solvent.Key words: epoxide, lithium perchlorate, β-aminoalcohols, solvent-free.

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.

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.
