Аннотация:We have developed a method for synthesis of N-substituted derivatives of indole from N-phenylalanine, including Fischer cyclization of the corresponding arylalkylhydrazones. The starting hydrazines were obtained by reduction of the corresponding nitrosamines. We have established that the optimum reduction method is to use metallic zinc in a methanol-hydrochloric acid system at low temperatures.
