  • Patent number: 7154005
    Abstract: This invention describes the reaction of an alpha fluoroalkyl ketone with a bis(trialkylsilyl)amide to give a stable N-trialkylsilyl imine. Treatment of the N-trialkylsilyl imine with an alcohol leads to solvolysis of the trialkylsilyl group and yields a stable mixture of an aminal and an imine in high yield. Catalytic reduction of this mixture, or of the individual components, in the presence of a chiral catalyst leads to a fluoroalkyl amine with high enantioselectivity and high yield.
