- Synthetic method of stable isotope deuterium-labeled alpha-amino acid
-
The invention relates to a synthetic method of stable isotope deuterium-labeled alpha-amino acid. According to the method, one or more deuterium-labeled halides are taken as labeled precursors and subjected to a reaction with phthalimide dimethyl malonate sodium salt, one or more deuterium-substituted phthalimide dimethyl malonate is obtained, and after hydrolysis, stable isotope deuterium-labeledalpha-amino acid is obtained. Compared with the prior art, the synthetic method is simple, safe and reliable, chemical purity of a product after simple separation and purification reaches 99% or higher, isotope abundance is 99% or higher, and the method can be applied to fields of protein metabolism tracing, food safety testing and the like.
