Williams, D. Bradley G.,Lawton, Michelle
, p. 6557 - 6560 (2006)
Epoxides are powerful starting materials for a range of useful materials and can be converted into, amongst others, amino alcohols. In this work, a range of epoxides was ring-opened using various alkyl- and arylamines under the action of aluminium triflat

Ca(CF3CO2)2 efficiently catalyzed the selective ring-opening of epoxides by amines leading to the synthesis of β-aminoalcohols. The reaction works well with various aromatic and aliphatic amines under solvent-free conditions. Corresponding β-aminoalcohols were obtained in excellent yields with high regioselectivity. The catalyst was easily prepared by reaction of CaH 2 in trifluoroacetic acid.
