In the presence of 5-10 mol % of 2, a series of terminal epoxides were reacted with phthalimide to form the ring-opening products, which, on treating with hydrazine to give 13 ? aminoalcohols in moderate yield.

Chiral β-amino alcohol and β-alkoxyl alcohol derivatives which are biologically important could be obtained by the ring-opening reactions of chiral terminal epoxides with amines and alkoxy anions.

1,1-Diphenylalkyllithium, obtained from the reaction of the corresponding alkyllithium with 1,1-diphenylethylene, reacted with optically active epichlorohydrin at -70 ℃, then at room temprature under stirring for several hours to yield chirally pure 4,4-diphenylsubstituted terminal alkene epoxide with >90% ee.
