Yttrium nitrate hexahydrate [Y(NO3)3·6H2O] 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 β-amino alcohols at low catalyst concentration.

Asymmetricsynthesis of N-aryloxazolidinones via dynamickineticresolution was developed. A ruthenium-based catalyst was used in the racemization of β-anilino alcohols, while Candida antarctica lipase B (CAL-B) was applied for two selective alkoxycarbonylations operating in cascade. Various N-aryloxazolidinone derivatives were obtained in high yields and good enantiopurities.
