  • Patent number: 5290957
    Abstract: A stereoselective process for preparing phenylisoserine derivatives is disclosed. Benzylamine is reacted with an agent for introducing a phenyl or a t-butoxycarbonyl group. The product undergoes double anionization and then is reacted with acrolein to provide a mixture of alcohol syn and anti diasteroisomers. The syn isomer is isolated by chromatography. Whereupon, the hydroxyl is protected and the product is oxidized to provide the phenylisoserine derivative.
