## Abstract α‐Deuterated tryptophan was prepared either by exchange of the α‐hydrogen of tryptophan or by hydrolysis and decarboxylation of ethyl 2‐formamido‐2‐carbethoxy‐3‐indole propionate, followed by treatment with CH~3~COO^2^H. α,β‐Dideuterated tryptophan was in turn synthetized from ethyl‐α‐a

Abstract
Syntheses of 5,7‐^3^H~2~ and 4,6‐^3^H~2~ tryptophan, respectively from 2,4,6‐^3^H~3~‐ and 3,5‐^3^H~2~‐aniline, were obtained by Fischer cyclization of suitable labelled phenylhydrazones.
