Asymmetric carbonyl addition with the homochiral ketimine derived from (+) or (-)-pinanone and benzylamine

【摘要】： <正> The carbonyl addition of the pinanone ketimine derived from (+) or (-)-2-hydroxy-pinan-3-one and benzylamine has been studied and the optically active α,β-substituted-β-aminoethanol deriva-tives were obtained in good chemical yields (36.5-69.5%) with optical purity ranging from 1.4% to99.9%.
