A process for the production of optically active (D- or L-) threo-3-(3,4-dihydroxyphenyl) serine, which comprises subjecting racemic threo-3-(3,4-dibenzyloxyphenyl) -N-carbobenzyloxyserine to optical resolution using as a resolving reagent an optically active amino alcohol derivative, and then subjecting the resulting optically active (D- or L-) threo-3-(3,4-dibenzyloxyphenyl) -N-carbobenzyloxyserine to hydrogenolysis.
一种生产光学活性(D-或 L-)硫代-3-(3,4-二羟基苯基)丝氨酸的工艺,包括将外消旋硫代-3-(3、(3,4-二苄氧基苯基) -N-苄氧羰基丝氨酸进行光学解析,解析试剂为具有光学活性的氨基醇衍生物,然后将得到的具有光学活性的(D-或 L-)苏氨酰-3-(3,4-二苄氧基苯基) -N-苄氧羰基丝氨酸进行氢解。
