The title compounds were synthesized starting from dimethyl (2S,3aR,8aS)-(+)-8-(phenylsulfonyl)hexahydrophyrrolo[2,3-b]indole-1,2-dicarboxylate. This compound on treatment with LDA followed by reaction with [14C]methyl iodide or [3H]methyl iodide gave the methyl substituted derivative which on treatment with trifloroacetic acid followed by hydrolysis with alkali gave the desired α-[14C]methyl- or [3H]methy-L-tryptophan, respectively, in 50-60% radiochemical yield.
标题化合物是从二甲基(2S,3aR,8aS)-(+)-8-(苯基磺酰)六氢吡咯并[2,3-b]吲哚-1,2-二羧酸酯合成的。该化合物与LDA反应后,再与[14C]碘甲烷或[3H]碘甲烷反应,得到甲基取代的衍生物。该衍生物与三氟乙酸反应后,再用碱水解,分别得到所需的α-[14C]甲基或[3H]甲基-L-色氨酸,放射化学产率为50-60%。
