Abstract

Изобретение относится к энзиматическому разделению R- и S-энантиомеров рацемического эфира 3-арил-4-аминомасляной кислоты, в котором арильная группа представлена фенилом (фенибут) или пара-хлорфенилом (баклофен), а сложноэфирная группа представлена насыщенной или ненасыщенной алкильной группой, содержащей от 2 до 8 углеродных атомов. Патентуемый метод получения состоит из следующих этапов: (1) селективная циклизация (S)-энантиомера рацемического эфира 3-арил-4-аминомасляной кислоты в 4(S)-арил-2-пирролидон в водном растворе в присутствии α-химотрипсина; (2) разделение 4(S)-арил-2-пирролидона и эфира 3(R)-арил-4-аминомасляной кислоты экстракцией после подкисления реакционной смеси до pH<2,0; (3) выделения 4(S)-арил-2-пирролидона из органической фазы и 3(R)-арил-4-аминомасляной кислоты из водной фазы и их последующее превращение в R- и S-стереоизомеры 3-арил-4-аминомасляной кислоты с помощью гидролиза в кислой среде.
