Histonedeacetylases (HDACs) allow histones to wrap DNA more tightly and finally lead to the repression of some tumor suppressor genes. Histonedeacetylaseinhibitors (HDACIs) have been proved to have effects on tumorigenesis and tumor progression. In this study, we reported the design, synthesis, and in vitro activity evaluation of novel PXD101 analogs with L‐phenylglycine‐containing cap as HDACIs

with diaryliodonium salts proceeds under mild conditions, enabling access to substituted S-aryl xanthates. The method exhibits good functional group tolerance and can be applied to the late-stage C–H functionalization of drug molecules. Divergent transformations of the resulting S-aryl xanthates provide rapid access to a range of medicinal chemistry-relevant organosulfur compounds.
通过过渡金属催化或 S N Ar 反应制备S -芳基黄原酸酯因其在所用条件下的进一步转化而变得复杂。相比之下,O-烷基黄原酸钾与二芳基碘盐的 S-芳基化反应在温和条件下进行,从而能够获得取代的S-芳基黄原酸。该方法表现出良好的官能团耐受性,可应用于药物分子的后期C-H功能化。由此产生的S -芳基黄原酸酯的不同转化提供了快速获得一系列与药物化学相关的有机硫化合物的途径。
