Method of producing (R)-2-amino-1-phenylethanol and opticaly active phenylserine and their halogen substituted products using tyrosine decarboxylase

Abstract

Tyrosine decarboxylase, or microorganisms of the genuses Enterococcus, Lactobacillus, Providencia, Fusarium, and Gibberella were reacted with a mixture of the enantiomers of threo-3-phenylserine or its halogen substitution products to produce (R)-2-amino-1-phenylethanol or its halogen substitution products. At the same time, one of the enantiomers of threo-3-phenylserine or its halogen substitution products were selectively left, and optically active threo-3-phenylserine or its halogen substitution products were produced. In addition, a novel material of 3-(3-chlorophenyl)serine, which is a substrate of the reaction in the present invention, was produced. (R)-2-amino-1-phenylethanol or its halogen substitution products, and optically active threo-3-phenylserine or its halogen substitution products can economically be produced on an industrial scale.
