reagent for peptide cyclisation and stapling. Little attention has been directed toward understanding the scope of this reaction. Traditional reaction optimisation relies on a one‐variable‐at‐a‐time approach, which can exclude important combined effects of reaction variables. This study initially explored base and solvent effects to inform a subsequent two‐level factorial design approach to understand how
六氟苯经历1,4-选择性硫醇-氟化物分解,是一种有吸引力的二硫键交联剂,用于肽的环化和装订。很少有人注意了解这一反应的范围。传统的反应优化依赖于一次可变的方法,该方法可以排除反应变量的重要综合影响。这项研究最初探索了碱和溶剂的影响,以为随后的两级因子设计方法提供信息,以了解如何在六氟苯模型反应中控制反应性和产物选择性。我们描述了选择性提供更高阶取代产物(例如1,2,4,5-四取代)的新条件,从而使六氟苯可能成为未来分支或多环肽系统的合适支架。此外,
