A metal-free iodine-catalyzed intramolecular amination has been developed for the practical synthesis of pyrrolo[2,3-b]indoles from readily available tryptophan esters. The transformation has been applied to a wide array of substrates and can be performed on gram scale under very mild conditions.
已经开发了一种无金属的碘催化的分子内胺化方法,用于从容易获得的色氨酸酯中实际合成吡咯并[2,3- b ]吲哚。该转化已应用于各种各样的底物,并且可以在非常温和的条件下以克为单位进行转化。
Nucleophilic substitution reactions were newly found to occur generally in the chemistry of 1-hydroxyindole derivatives. Its application to the synthesis of a phytoalexin, brassicanal A, is reported.
