The synthesis of two isotopomers of L-DOPA labelled selectively with tritium is reported. In the intermediate step [3S-3H]-, and [3′,5′-3H2]-L-tyrosine, have been obtained using a combination of chemical and enzymatic methods. The labelled isotopomers of L-tyrosine, L-Tyr, have been converted into, [3S-3H]-, and [5′-3H]-L-DOPA using the enzyme mushroom tyrosinase (monophenol oxidase, EC 1.14.18.1)
