  Synthesis and biological evaluation of novel C-indolylxylosides as sodium-dependent glucose co-transporter 2 inhibitors

  摘要：

  Sodium-dependent glucose co-transporter 2 (SGLT2) inhibitors are the current focus on the indication for the management of hyperglycemia in diabetes. Here, a novel series of C-linked indolylxyloside-based inhibitors of SGLT2 has been discovered. Structure-activity relationship studies revealed that substituents at the 7-position of the indole moiety and a p-cyclopropylphenyl group in the distal position were necessary for optimum inhibitory activity. The pharmacokinetic study demonstrates that the most potent compound 1i is metabolically stable with a low clearance in rats. In further efficacy study, 1i is found to significantly lower blood glucose levels of streptozotocin (STZ)-induced diabetic rats. (C) 2012 Elsevier Masson SAS. All rights reserved.

  芳香族羧酸的无过渡金属脱羧溴化反应†

  摘要：

  在过去的一个世纪中，将脂肪酸转化为卤代烷的方法取得了显着进展，然而，芳香族酸的类似脱羧溴化仍然是一个长期的挑战。开发有效的芳基溴化物合成方法非常重要，因为它们是合成中的通用试剂，并且存在于许多功能分子中。在此，我们报告了芳香族酸的无过渡金属脱羧溴化反应。该反应适用于许多富含电子的芳族和杂芳族酸，这些酸先前已被证明是Hunsdiecker型反应的不良底物。此外，我们的初步机理研究表明，自由基中间体不参与该反应，这与经典的Hunsdiecker型反应性相反。全面的，

  Electro‐Oxidative Coupling of Azoles with 2‐ and 3‐Haloindoles/Thiophenes Providing Access to 2/3‐Halo(Azol‐1‐Yl)Indoles/Thiophenes

  摘要：

  AbstractThis report discloses an electrochemical oxidative C−H/N−H cross coupling method for the synthesis of C‐2/C‐3 azolated halo‐indoles/thiophenes under metal catalyst‐free and external chemical oxidant free condition. Hydrogen gas was the only byproduct of this C−H/N−H cross‐coupling reaction. The synthetic utility of this electrochemical approach is highlighted by its easy scalabity and compatibility with highly functional indoles and azoles. The retention of halogen on the heterocycles could serve as a useful functional group for future late‐stage modifications.magnified image

• Hydrogen‐Bond‐Donor Solvents Enable Catalyst‐Free (Radio)‐Halogenation and Deuteration of Organoborons
  作者：Yi Yang、Xinyan Gao、Xiaojun Zeng、Junbin Han、Bo Xu

  DOI：10.1002/chem.202003919

  日期：2021.1.18

  A hydrogen bond donor solvent assisted (radio)halogenation and deuteration of organoborons has been developed. The reactions exhibited high functional group tolerance and needed only an ambient atmosphere. Most importantly, compared to literature methods, our conditions are more consistent with the principals of green chemistry (e.g., metal‐free, strong oxidant‐free, more straightforward conditions)

  halogenation of arenes and heterocycles with N-halosuccinimides in fluorinated alcohols is disclosed. Under mild condition reactions, a wide diversity of halogenated arenes are obtained in good yields with high regioselectivity. Additionally, the versatility of the method is demonstrated by the development of one-pot sequential halogenation and halogenation-Suzuki cross-coupling reactions.
