A deaminative reductive coupling of amino acid pyridinium salts with aryl bromides has been developed to enable efficient synthesis of noncanonical amino acids and diversification of peptides. This method transforms natural, commercially available lysine, ornithine, diaminobutanoic acid, and diaminopropanoic acid to aryl alanines and homologated derivatives with varying chain lengths. Attractive features
已经开发出氨基酸吡啶鎓盐与芳基溴的脱氨基还原偶联,以实现非规范氨基酸的有效合成和肽的多样化。该方法将天然的市售赖氨酸、鸟氨酸、二氨基丁酸和二氨基丙酸转化为芳基丙氨酸和具有不同链长的同系衍生物。有吸引力的特性包括横向扩展的能力、对药物相关(杂)芳基和双正交官能团的耐受性,以及超越单体氨基酸对短肽和大环肽底物的适用性。这项工作的成功依赖于高通量实验来确定互补反应条件,这些条件被证明对于实现广泛的芳基溴与一系列氨基酸和肽底物(包括大环肽)的偶联至关重要。
