Carbohydrates play essential roles in various physiological and pathological processes. Trifluoromethylated compounds have wide applications in the field of medicinal chemistry. Herein, we report a practical and efficient trifluoromethylation of glycals by an electrochemical approach using CF3SO2Na as the trifluoromethyl source and MnBr2 as the redox mediator. A variety of trifluoromethylated glycals
碳水化合物在各种生理和病理过程中发挥着重要作用。三氟甲基化化合物在药物化学领域有着广泛的应用。在此,我们报道了一种使用CF 3 SO 2 Na 作为三氟甲基源和MnBr 2作为氧化还原介体的电化学方法对糖醛进行实用且有效的三氟甲基化。多种带有不同保护基团的三氟甲基化糖以 60-90% 的收率获得,具有高区域选择性。CF 3自由基的成功捕获表明该反应涉及自由基机理。

Synthesis of potent adenosine A2A and A3 receptoragonist from the modification of adenosine-5′-N-ethylcarboxamide (NECA) has been reported. Diastereoisomer possessing an (R)-3,4-dihydro-2H-pyranyl (DHP) moiety exhibited the highest affinity at the A2A and A3 receptors. The key steps involve the synthesis of (R)-3,4-dihydro-2H-pyran-2-carboxaldehyde (7), which was obtained through the enzyme-catalyzed
