    摘要: A process for producing optically active 1-halo-3-amino-4-phenyl-2-butanol derivatives from optically active 1-halo-3-amino-4-phenyl-2-butanone derivatives stereoselectively in a high yield by bringing the butanone derivatives into contact with microorganisms.

    摘要: Processes for efficiently producing α-halo ketones, α-halohydrins and epoxides on an industrial scale. The prosesses include one for producing an α-halo ketone of general formula (3) by decarboxylating a product of reaction between a carboxilic acid derivative of general formula (1) and a metal enolate prepared from an α-haloacetic acid of general formula (2) or an acceptable salt thereof, one for producing an by reducing the α-halo ketone (3), and one for producing an epoxide (13) by treating the α-halohydrin (11) with a base to effect ring closure. The above prosesses are particularly suitable for producing optically active α-halo ketones, α-halohydrins and epoxides from the corresponding α-amino acid derivatives.
