Abstract

Efficient methods for synthesising L‐[methy‐ ^13^C]methionine from [^13^C]iodomethane and L‐methionine, and L‐[3,4‐^13^C~2~] methionine from [^13^C~2~]ethene, are described; the preparation of [3,3‐^2^H~2~]methionine and [2,3,3‐^2^H~3~]methionine from methionine by an exchange method is detailed.
