A facile route has been established for the synthesis of indole-substituted (S)-tryptophans from corresponding indoles, which utilizes a chiral auxiliary-facilitated Strecker amino acid synthesis strategy. The chiral auxiliary reagents evaluated were (S)-methylbenzylamine and related derivatives. To illustrate the robustness of the method, eight optically pure (S)-tryptophan analogues were synthesized
已经建立了从相应的吲哚合成吲哚取代的(S)-色氨酸的简便路线,该路线利用了手性辅助促进的Strecker氨基酸合成策略。评价的手性辅助试剂是(S)-甲基苄胺和相关衍生物。为了说明该方法的鲁棒性,合成了八个光学纯的(S)-色氨酸类似物,随后将其用于有效的抗菌剂精氨酸A及其类似物的会聚合成。
