Abstract
[α -15N]-dl-tryptophan was synthesized by the use of Al-Ni alloy catalytichydrogenation from 15N-glycine via several steps. The overall yield of the finalproduct was 46.9% and the abundance of 15N was about 93%. The physicochemicalproperties of the synthetic compound obtained were the same as those of the standardtryptophan. Its structure were confirmed by the elemental analyses, MS, UV andpaper chromatography.
