Nπ-1-Adamantyloxymethylhistidine, His(Nπ-1-Adom) was prepared, and the properties of the 1-Adom group were examined. 1-Adom group can be easily removed by TFA ; it is stable to 20% piperidine/DMF and 1N NaOH. His(Nπ-1-Adom) derivatives can suppress racemization during coupling reaction. TRH was synthesized using His(Nπ-1-Adom), successfully.
制备Nπ-1-金刚烷氧基甲基组氨酸His(Nπ-1-Adom),并检查1-Adom基团的性质。 1-Adom基团可以很容易地被TFA去除;对 20% 哌啶/DMF 和 1N NaOH 稳定。 His(Nπ-1-Adom)衍生物可以抑制偶联反应过程中的外消旋化。利用His(Nπ-1-Adom)成功合成了TRH。
