Disclosed are a process for preparation of an optically active 7-substituted 3-(2-aminopropyl)indole compound and an intermediate therefor. In the above preparation process, 7-substituted indole is reacted with L- or DL-serine in the presence of a tryptophan-synthesizing enzyme originating in microorganisms to form corresponding 7-substituted L-tryptophan, and it is subjected, if necessary, to reduction, protection, exchange and elimination.
本发明公开了一种具有光学活性的 7-取代 3-(2-
氨基丙基)
吲哚化合物及其中间体的制备方法。在上述制备工艺中,7-取代的
吲哚与 L-或
DL-丝氨酸在一种源于微
生物的
色氨酸合成酶的存在下发生反应,生成相应的 7-取代的
L-色氨酸,并在必要时进行还原、保护、交换和消除。
