This invention relates to generally inhibiting histone deacetylase (“HDAC”) enzymes (e.g., HDAC1, HDAC2, and HDAC3) using compounds of formula (I),
wherein the substituents are as defined herein.
Aryl and heteroaryl iodides have been efficiently converted into the corresponding thioacetates in cyclopentyl methylether (CPME), a green solvent, under Cu catalysis. The chemoselectivity of the reaction is mainly controlled by electronic factors, enabling the conversion of both electron-rich and electron-deficient substrates into the corresponding thioacetates in good to excellent yields. The products
在铜催化下,芳基和杂芳基碘化物在绿色溶剂环戊基甲基醚(CPME)中有效转化为相应的硫代乙酸酯。该反应的化学选择性主要受电子因素控制,使富电子和缺电子底物都能以良好至优异的产率转化为相应的硫代乙酸盐。产物可以很容易地脱保护为相应的硫醇盐,以进行额外的原位合成转化。令人惊讶的是,尽管 CPME 的介电常数相对较低,但在微波辐射条件下进行时,反应速率显着提高。该合成方法在绿色溶剂 CPME 中使用安全且廉价的 CuI 预催化剂,表现出对官能团的显着耐受性、温和的反应条件和广泛的底物范围。非水后处理允许完全回收催化剂和溶剂,使该方法成为 C(sp2) 硫官能化的环境可持续方案。此外,该反应显示出与碘化物与氯化物和溴化物竞争的选择性交叉偶联,使其可用于多步合成。为了证明该方法的潜力,将其应用于光致变色二噻吩乙烯的高产率合成,此前尚未报道过选择性合成。
