Title:
PROCESS FOR PRODUCING OPTICALLY ACTIVE HALOPROPANEDIOL DERIVATIVE
Document Type and Number:
WIPO Patent Application WO/2003/018523
Kind Code:
A1
Abstract:
A process for easily producing from an inexpensive material an optically active halopropanediol derivative which is useful as an intermediate for medicines. An inexpensively available propargyl alcohol derivative is reacted with a hypohalogenous acid to convert the derivative into a di− or trihalohydroxyacetone derivative. This derivative is hydrogenated in the presence of a transition metal catalyst to produce a monohalohydroxyacetone derivative. Furthermore, a source of an enzyme having the ability to stereoselectively reduce the carbonyl groups of halohydroxyacetone derivatives is used to stereoselectively reduce the halohydroxyacetone derivative to produce an optically active halopropanediol derivative.
