Abstract: 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.

Abstract: An object of the present invention is to provide a process for producing a beta -amino- alpha -hydroxy acid derivative via efficient and industrially utilizable steps. The present invention provides a process for producing a beta -amino- alpha -hydroxy acid derivative represented by the general formula (2) given below which comprises hydrolyzing an alpha -amino- alpha ', alpha '-dihaloketone derivative of the general formula (1) given below in the presence of a base, followed by protecting the amino group or without protecting the same.

Abstract: Processes for efficiently producing alpha -halo ketones, alpha -halohydrins and epoxides on an industrial scale. The prosesses include one for producing an alpha -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 alpha -haloacetic acid of general formula (2) or an acceptable salt thereof, one for producing an by reducing the alpha -halo ketone (3), and one for producing an epoxide (13) by treating the alpha -halohydrin (11) with a base to effect ring closure. The above prosesses are particularly suitable for producing optically active alpha -halo ketones, alpha -halohydrins and epoxides from the corresponding alpha -amino acid derivatives. R COA
