Novel Benzo[b]thiophene Derivatives as New Potential Antidepressants with Rapid Onset of Action
摘要:
We report benzo[b]thiophene derivatives synthesized according 10 a dual strategy. 8j, 9c, and 9e with affinity values toward 5-HT(7)R and 5-HTT were selected to probe their antidepressant activity in vivo using the forced swimming text (FST). The results slowed significant antidepressant activity after chronic treatment. 9c was effective in reducing the immobility time in FST even after acute treatment. These findings identify these compounds as a new class of antidepressants with a rapid onset of action.

activities by interacting with proteins and nucleic acids. Then, synthesis of such compounds is critical for the development of drugs. Unsymmetric HetAr-X-HetAr′ compounds were efficiently synthesized by rhodium-catalyzed heteroaryl exchangereactions, which involved equilibrium control by judicious design of organic heteroaryl reagents. This method allows synthesis of unsymmetric HetAr–O–HetAr′, HetAr–S–HetAr′

Fluorinating Pyridine Appending fluorine substituents to carbon centers is commonly used to tune small-molecule properties in pharmaceutical and agrochemical research. However, fluorinations often require the use of corrosive, hazardous reagents. Fier and Hartwig (p. 956) present an unusually mild and convenient protocol for fluorinating carbon sites adjacent to nitrogen in pyridines and related nitrogen-bearing

aromatic carboxylic acids exist in great structural diversity from nature and synthesis. To date, the synthetically valuable decarboxylative functionalization of benzoic acids is realized mainly by transition-metal-catalyzed decarboxylative cross couplings. However, the high activation barrier for thermal decarboxylative carbometalation that often requires 140 °C reaction temperature limits both the
丰富的芳香羧酸存在于自然界和合成中的巨大结构多样性中。迄今为止,苯甲酸的具有合成价值的脱羧官能化主要是通过过渡金属催化的脱羧交叉偶联来实现的。然而,通常需要 140 °C 反应温度的热脱羧碳金属化的高活化能垒限制了底物范围以及可以维持这种条件的合适反应的范围。许多反应,例如,为脂肪族羧酸很好地开发的脱羧氟化,对于芳香族对应物来说,用当前的反应化学是无法实现的。这里,我们报告了一种概念上不同的方法,通过低势垒光诱导配体到金属电荷转移 (LMCT) 启用自由基脱羧碳金属化策略,该策略生成假定的高价芳基铜 (III) 配合物,从中可以发生通用的轻松还原消除。我们证明了我们的新方法适用于解决以前未实现的苯甲酸的一般脱羧氟化。
