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 triflate as a catalyst. This catalyst was found to be highly active, producing the desired amino alcohol products in high yields with low catalyst loadings. Additionally, it was shown that the aluminium triflate catalyst is recyclable by simple extraction into water and may be re-used several times. (c) 2006 Elsevier Ltd. All rights reserved.

Abstract Various β -aminoalcohols were prepared by the ring opening reaction of epoxides with aromatic amines in the presence of Fe(III) substituted Wells–Dawson type polyoxometalate, α 2 -[(n-C 4 H 9 ) 4 N] 7 P 2 W 17 FeO 61 ·3H 2 O, as an efficient catalyst. The reaction was performed under neutral condition at room temperature and afforded the corresponding products in high to excellent yields.
