Novel indole derivatives of the general formula I
can be obtained by reacting, directly or indirectly, N,N-dimethyl-3-indolemethylamine with a Schiff base of the general formula II,
In these formulae R' is cyano or methoxycarbonyl, ethoxycarbonyl, propoxycarbonyl or butoxycarbonyl, and 0 is phenyl. The reaction is performed in the presence of a base, with or without the use of a catalyst. The successive hydrolysis of the indole derivatives of the general formula I in the presence of an acid and of a base gives tryptophane.
通式 I 的新型吲哚衍生物
通过直接或间接使 N,N-二甲基-3-吲哚甲胺与通式 II 的希夫碱反应,可得到通式 I 的新型吲哚衍生物、
在这些式中,R'是氰基或甲氧羰基、乙氧羰基、丙氧羰基或丁氧羰基,0 是苯基。反应在碱存在下进行,可使用或不使用催化剂。通式 I 的吲哚衍生物在酸和碱存在下连续水解,可得到色氨酸。
