  In an in-house screening, 1H-pyrrolo[2,3-b]pyridine scaffold was found to have high inhibition on TNIK. Several series of compounds were designed and synthesized, among which some compounds had potent TNIK inhibition with IC50 values lower than 1 nM. Some compounds showed concentration-dependent characteristics of IL-2 inhibition. These results provided new applications of TNIK inhibitors and new prospects

  simple route towards the synthesis of hindered ethers, in which electrochemical oxidation is used to liberate high-energy carbocations from simple carboxylic acids. These reactive carbocation intermediates, which are generated with low electrochemical potentials, capture an alcohol donor under non-acidic conditions; this enables the formation of a range of ethers (more than 80 have been prepared here)

  受阻醚在各种应用中都具有很高的价值；然而，它们仍然是未充分探索的化学空间领域，因为它们难以通过常规反应合成 1,2。这种基序在药物化学中非常令人垂涎，因为对醚键的广泛取代可以防止可能导致体内快速降解的不需要的代谢过程。在这里，我们报告了合成受阻醚的简单途径，其中电化学氧化用于从简单的羧酸中释放高能碳正离子。这些反应性碳阳离子中间体以低电化学势生成，在非酸性条件下捕获醇供体；这使得能够形成一系列醚（这里已经制备了 80 多种），否则很难获得。碳正离子也可以被简单的亲核试剂拦截，导致受阻醇甚至烷基氟化物的形成。评估该方法能够规避制备 12 种化学支架时遇到的合成瓶颈，从而提高所需产品的产率，此外还显着减少了制备所需的步骤数量和劳动量。分子探针的使用和动力学研究的结果支持了所提出的机制和添加剂在所检查条件下的作用。我们在这里报告的反应流形证明了电化学在温和条件下获得高反应性中间体的能力，反过来，

  Olefins are prevalent substrates and functionalities. The synthesis of olefins from readily available starting materials such as alcohols, amines and carboxylic acids is of great significance to address the sustainability concerns in organic synthesis. Metallaphotoredox-catalyzed defunctionalizations were reported to achieve such transformations under mild conditions. However, all these valuable strategies

  烯烃是普遍的底物和功能。从醇、胺和羧酸等易得起始原料合成烯烃对于解决有机合成中的可持续性问题具有重要意义。据报道，金属光氧化还原催化的去官能化可以在温和条件下实现这种转变。然而，所有这些有价值的策略都需要过渡金属催化剂、配体或昂贵的光催化剂，并且仍然存在控制区域选择性和立体选择性的挑战。在此，我们提出了一种由电子供体-受体（EDA）配合物实现的根本不同的策略，用于从这些简单且易于获得的起始材料选择性合成烯烃。该转化是通过用碱金属盐对活化底物的 EDA 络合物进行光活化，然后从原位生成的烷基自由基中消除氢原子来进行的。该方法操作简单直接，不含光催化剂和过渡金属，并表现出高区域选择性和立体选择性。
