δ-thiolation of aliphatic α-amino acids catalyzed by a Pd(II)/Ag(I) system. This reaction employs disulfides as thiolating agents and N-COPy as directing group, providing valuable non-proteinogenic amino acid derivatives in moderate to good diastereoselectivities and yields. Remarkably, the method is also suitable for the late-stage functionalization of a dipeptide. Experimental and DFT studies have provided
在此,我们报告了一种由 Pd(II)/Ag(I) 系统催化的脂肪族 α-氨基酸选择性 δ-硫醇化的方案。该反应使用二硫化物作为硫醇化剂,使用N -COPy作为导向基团,以中等至良好的非对映选择性和产率提供有价值的非蛋白氨基酸衍生物。值得注意的是,该方法也适用于二肽的后期功能化。实验和 DFT 研究为控制过程选择性和确定银盐的关键作用的机制和潜在因素提供了重要的见解。
