Zn/Cu(OTf)-mediated addition of alkyl bromides to dehydroalanine (Dha) derivatives including dipeptides and tripeptides in good to high yields under an aqueous medium was developed. This protocol allows selective and biocompatible access to various amino acid units from Dha derivatives.
开发了在水介质中,通过 Zn/Cu(OTf)介导,使烷基溴化物与包括二肽和三肽在内的脱水氨酸(Dha)衍生物加成,以高产率得到良好至高产率的产物。该方案允许从 Dha 衍生物中选择性和生物相容性地获得各种氨基酸单元。
