Substituted urea/thiourea derived from fluoxetine as potent appetite suppressants
摘要:
A series of urea and thiourea analogues of fluoxetine (5-17) were synthesized and evaluated for their anorexigenic and antidepressant activities. The related conformationally restrained analogues (20-23) were also prepared for structure-activity relationship (SAR) studies. Many of these derivatives (5, 6, 8, 10, 12, 13, 16, and 23) exhibited significant anorexigenic activity and interestingly were devoid of antidepressant activity, thus emerging as a promising tool for further research work.

synthesis of thioethers by forging C(aryl)-S bond via an aryne mechanism. The active aryne species can be generated from o-diiodoarenes and NaH in THF at room temperature, then lead to the arylations of a wide range of aryl thiols and thioureas. Different from transition metal-catalyzed cross-couplingreactions, no disubstituted byproduct is formed in our protocol. The o-iodoaryl thioether products are
在此,我们报道了一种通过芳基机理形成 C(芳基)-S 键来合成硫醚的方法。室温下,邻二碘芳烃和 NaH 在 THF 中可以生成活性芳炔,然后导致多种芳基硫醇和硫脲的芳基化。与过渡金属催化的交叉偶联反应不同,我们的方案中没有形成双取代的副产物。邻碘芳基硫醚产品是可以转化为药学上感兴趣的分子的中间体。
