chalcogenation of tryptophan-containing peptides with disulfides/diselenides in moderate to good yields. It comprises broad substrate scope, functional group diversity, late-stage modification of drug molecules, and various valuable synthetic transformations, including room temperature easy removal of the picolinamide auxiliary, which could be applicable to tune the structure and function of peptides.
该报告描述了钯催化的含色氨酸肽与二硫化物/二硒化物的后期硫属化反应,产率中等至良好。它包括广泛的底物范围、官能团多样性、药物分子的后期修饰以及各种有价值的合成转化,包括室温下轻松去除吡啶酰胺辅助剂,可用于调整肽的结构和功能。
