  Nickel-Catalyzed Cross-Coupling of Potassium Aryl- and Heteroaryltrifluoroborates with Unactivated Alkyl Halides

  摘要：

  A method for the cross-coupling of alkyl electrophiles with various potassium aryl- and heteroaryltrifluoroborates has been developed. Nearly stoichiometric amounts of organoboron species could be employed to cross-couple a large variety of challenging heteroaryl nucleophiles. Several functional groups were tolerated on both the electrophilic and the nucleophilic partners. Chemoselective reactivity of C(sp(3))-Br bonds in the presence of C(sp(2))-Br bonds was achieved.

  heterogeneous copper-catalyzed chlorodeboronation of arylboronic acids with inexpensive N-chlorosuccinimide (NCS) was achieved in MeCN in the presence of 10 mol% of L-proline-functionalized MCM-41-immobilized copper(I) complex [MCM-41-L-proline-CuCl] under mild conditions, yielding a variety of aryl chlorides in excellent yields. This method proved to be tolerant of a broad range of functional groups and particularly

  Due to the limitations of existing anti-EV71 targets, we have been eager to discover a new anti-EV71 agent based on mTOR (the mammalian target of rapamycin), which is an important target for finding antiviral agents based on host cells. Torin2 is a second-generation ATP competitive mTOR kinase inhibitor (IC50 = 0.25 nM). Our research team tested the anti-EV71 activity of Torin2 in vitro for the first

  由于现有抗EV71靶标的局限性，我们一直渴望发现一种基于mTOR（雷帕霉素的哺乳动物靶标）的新型抗EV71剂，这是寻找基于宿主细胞的抗病毒剂的重要靶标。Torin2是第二代ATP竞争性mTOR激酶抑制剂（IC 50  = 0.25 nM）。我们的研究团队首次在体外测试了Torin2的抗EV71活性。结果表明，Torin2具有显着的抗EV71活性（IC 50  = 0.01μM）。在这项研究中，合成了三十种新颖的Torin2衍生物，并评估了其抗EV71活性。其中11a，11b，11d，11e和11m显示了与Torin2类似的活动。图11e显示了最有效的活性，最接近Torin2的IC 50值为0.027μM，并且显示了有效的mTOR激酶抑制活性。分子建模研究表明，11e通过氢键与Val2240和Lys2187相互作用，并与受体具有良好的匹配性。此外，一项机理研究表明，大多数化合物对mTOR途径

The reaction of meso‐substituted purpurinimide with N‐bromosuccinimide regioselectively introduced a bromo functionality at the 20‐position, which on further reaction with a variety of boronic acids under Suzuki reaction conditions yielded the corresponding meso‐substituted analogues. Interestingly, the free base and the metalated
