Yttrium nitrate hexahydrate [Y(NO3)(3)center dot 6H(2)O] was found to be an efficient catalyst for selective ring opening of epoxides with aliphatic, aromatic, and heteroaromatic amines at room temperature under solvent-free conditions. The system tolerated a variety of hindered and functionalized epoxides/amines and afforded the desired P-amino alcohols at low catalyst concentration. (C) 2008 Elsevier Ltd. All rights reserved.
