Lanthanide(lll) trifluoromethanesulfonates (triflates), such as Yb(OTf)3, Nd(OTf)3 and Gd(OTf)3, catalyze in a extraordinarily efficient way the aminolysis of 1,2-epoxides, affording the corresponding beta-amino alcohols, at room temperature and in a non-protic solvent (CH2Cl2 or toluene), in very good yields. The reactions are completely anti stereoselective and highly regioselective.

Abstract
Lanthanide(lll) trifluoromethanesulfonates (triflates), such as Yb(OTf)3, Nd(OTf)3 and Gd(OTf)3, catalyze in a extraordinarily efficient way the aminolysis of 1,2-epoxides, affording the corresponding beta-amino alcohols, at room temperature and in a non-protic solvent (CH2Cl2 or toluene), in very good yields. The reactions are completely anti stereoselective and highly regioselective.File in questo prodotto:
