An Improved Method for Decarboxylating Indole-2-Carboxylic Acids and Its Application in the Synthesis of 7-Amino-DL-Tryptophan

10.1139/v64-189

The study presents an improved method for decarboxylating indole-2-carboxylic acids, specifically focusing on the synthesis of 7-amino-DL-tryptophan. Key chemicals involved include 7-nitroindole-2-carboxylic acid, which is decarboxylated using S,S-dimethylacetamide and a copper salt catalyst to produce 7-nitroindole. This compound serves as an intermediate in the synthesis of 7-amino-DL-tryptophan. Other intermediates like 7-nitrogranzine and ethyl a-acetamido-a-carbethoxy-α-(7-amino-5-indolyl)propionate are also synthesized and reduced to obtain the final product. The study highlights the efficiency and simplicity of the dimethylacetamide method for decarboxylation compared to the conventional quinoline procedure.
