N-acyl-DL-3-(3,4-dihydroxyphenyl)serine or a catecholic hydroxyl-protected derivative thereof is stereospecifically de-acylated by reaction with a microorganism of Streptomyces or Streptoverticillium having an acylase or with an extract of said microorganism containing said acylase, to produce L-3-(3,4-dihydroxyphenyl)serine or the hydroxyl-protected derivative thereof, with the N-acyl-D-3-(3,4-dihydroxyphenyl)serine compound remaining unaltered. The L-3-(3,4-dihydroxyphenyl)-serine compound so produced can be separated from the N-acyl-D-3-(3,4-dihydroxyphenyl)serine compound owing to its different properties.
将 N-酰基-DL-3-(3,4-二羟基苯基)丝氨酸或其羟基保护的儿茶酚衍生物与具有酰化酶的链霉菌或链孢霉微生物或含有所述酰化酶的所述微生物提取物反应,进行立体定向脱酰化、生成 L-3-(3,4-二羟基苯基)丝氨酸或其羟基保护衍生物,而 N-酰基-D-3-(3,4-二羟基苯基)丝氨酸化合物保持不变。由于 N-酰基-D-3-(3,4-二羟基苯基)丝氨酸化合物具有不同的性质,因此可以将这样制得的 L-3-(3,4-二羟基苯基)丝氨酸化合物与 N-酰基-D-3-(3,4-二羟基苯基)丝氨酸化合物分开。
