    Palladium-catalyzed direct functionalization of benzoxazoles with alkenyl iodides
    摘要:
    A straightforward procedure for the palladium-catalyzed direct functionalization of benzoxazoles with alkenyl iodides is described. The reactions employ a Pd(II)-precatalyst and use 'on water' conditions to achieve the ready union of a range of di- and tri-substituted alkenyl iodides with a small range of benzoxazoles.

    缩醛与 TESOTf-Base 组合的反应;中间体及高效混合缩醛形成的推测
    摘要:
    我们在这里报告了醛的缩醛出人意料的高度化学选择性脱保护。在 0 摄氏度的 CH2Cl2 中用 TESOTf-2,6-二甲基吡啶或 TESOTf-2,4,6-可力丁处理来自醛的缩醛化合物,然后在相同温度下进行 H2O 处理,导致缩醛功能转化为醛功能。该反应具有普遍性,适用于许多缩醛化合物。使用各种碱的研究揭示了反应并达到了TESOTf-碱的最佳组合。它非常温和且具有高度化学选择性,并且在弱碱性条件下进行。然后,许多官能团如烯丙醇、甲硅烷基醚、乙酸酯、甲基醚、三苯甲基 (Tr) 醚、1,3-二硫杂环戊烷、甲基酯和叔丁基酯可以在这些条件下存活。此外,这种方法可以在缩酮存在的情况下选择性地对缩醛进行脱保护,这是最典型的特征,尽管这种化学选择性很难通过其他先前报道的方法实现。包括 MS 和 NMR 研究在内的对反应的详细研究揭示了确定中间体吡啶鎓型盐结构的反应机制。这些中间体具有弱的亲电性,并成功地应用于高产率的混合缩醛的有效形成。

  • Unexpected Highly Chemoselective Deprotection of the Acetals from Aldehydes and Not Ketones:  TESOTf−2,6-Lutidine Combination

    corresponding aldehydes. Of course, the compounds, which have both acetal and hydroxyl functions afforded the compounds obtained by the usual silylation of an alcohol and deprotection of an acetal without any problem. However, deprotection of the ketals from ketones was not observed during the conversion reaction of acetals from aldehydes. This chemoselectivity was confirmed in the reactions of the compounds
    缩醛官能团被认为是羰基的良好保护基团。尽管已经开发了许多将缩醛脱保护为羰基官能团的方法,但没有方法可以在缩酮存在下对缩醛脱保护,因为通过来自缩酮的更稳定的阳离子或自由基中间体,通常的酸性或自由基反应更容易发生。另一方面,这种新方法可以以与先前报告中描述的方法相反的方式进行。即,该方法可以在缩酮的存在下使脂肪族缩醛脱保护。反应条件对于甲硅烷基化是常见的,即 TESOTf-2,6-二甲基吡啶组合。尽管 TMSOTf-2,6-二甲基吡啶组合也可以使缩醛脱保护,但它缺乏从醛和酮中脱除缩醛的化学选择性。在 CH2Cl2 中用 TESOTf 和 2,6-二甲基吡啶处理缩醛,然后进行 H2O 处理,得到相应的醛。当然,具有缩醛和羟基官能团的化合物可以毫无问题地提供通过醇的通常甲硅烷基化和缩醛的脱保护获得的化合物。然而,在缩醛与醛的转化反应过程中未观察到缩酮与酮的脱保护。这种化学选择性在同一分子中含有缩醛

    4'-Ethynylostavudine derivatives according to the invention substituted at 4'-ethynylostavudine 5'-O-position with 12-tetradodecanoyl, 12-bromododecanoyl, 12-methoxydodecanoyl, 12-ethylothiododecanoyl, or 12-azidododecanoyl group (represented by the symbols WA37, WA38, WA40, WA42, WA39) in deClPhR™ cells exert very high antiviral activity against the wild type HIV-1 strain, as well as against its drug and multidrug resistant strains, without any citotoxicty at the therapeutic concentrations (CC50 >200 µM). These compounds, because of their very low toxicity may be applied at all phases of AIDS, even at the final phase when the T4 lymphocytes level in patients drops down below 200/µL of peripheral blood. The 2',3'- didehydro-3'-deoxy-4'-ethynylothymidine derivatives, according to the invention, are synthesized by the transformation of the known compound 4'-ethynylostavudine (WA32, wherein R represents hydrogen).

    A series of DAG-lactones with polar 3-alkylidene substituents have been investigated as PKC-alpha ligands and antitumor agents. Extensive analysis of structure-activity relationships for the 3-alkylidene chain revealed that polar groups such as ether, hydroxyl, aldehyde, ester, acyloxy, and amido were tolerated with similar binding affinities and reduced lipophilicities compared to the corresponding unsubstituted alkylidene chain. Among the derivatives, compounds 5, 6 and 8 with an ether type of side chain showed high binding affinities in range of K-i = 3-5 nM and excellent antitumor profiles, particularly against the colo205 colon cancer and the K562 leukemia cell lines.
