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.

Lewis Acid Catalyst

Anhydrous titanium(III) chloride was found to be a simple and efficient Lewis acid catalyst for ring opening of epoxides at ambient temperature. The reaction proceeded smoothly with anilines as well as azide ion as nucleophiles to give the corresponding β-amino alcohols and β-azido alcohols in moderate to good yields.
