  Deprotometalation–iodolysis and computed CH acidity of 1,2,3- and 1,2,4-triazoles. Application to the synthesis of resveratrol analogues

  摘要：

  1-Aryl-and 2-aryl-1,2,3-triazoles were synthesized by N-arylation of the corresponding azoles using aryl iodides. The deprotometalations of 1-phenyl-1,2,3-triazole and -1,2,4-triazole were performed using a 2,2,6,6-tetramethylpiperidino-based mixed lithium-zinc combination and occurred at the most acidic site, affording by iodolysis the 5-substituted derivatives. Dideprotonation was noted from 1-(2-thienyl)-1,2,4-triazole by increasing the amount of base. From 2-phenyl-1,2,3-triazoles, and in particular from 2-(4-trifluoromethoxy) phenyl-1,2,3-triazole, reactions at the 4 position of the triazolyl, but also ortho to the triazolyl on the phenyl group, were observed. The results were analyzed with the help of the CH acidities of the substrates, determined in THF solution using the DFT B3LYP method. 4-Iodo-2-phenyl-1,2,3-triazole and 4-iodo-2-(2-iodophenyl)-1,2,3-triazole were next involved in Suzuki coupling reactions to furnish the corresponding 4-arylated and 4,2'-diarylated derivatives. When evaluated for biological activities, the latter (which are resveratrol analogues) showed moderate antibacterial activity and promising antiproliferative effect against MDA-MB-231 cell line.

  sterically varied coumarin–functionalized imidazolium salts bearing bromide (5–7) and hexafluorophosphate anions (8–10) have been prepared and used as NHC precursors. The salts have been characterized by both, spectroscopic and analytical techniques. A hexafluorophosphate salt 9 was also studied for its structure using the single-crystal XRD technique. The salts that indeed, generate carbene that trap Cu(I)

  第一行过渡金属催化的有机转化由于其步骤经济和原子经济的方法而在现代合成有机化学中引起了极大的兴趣。因此，通过 C-H 或 N-H 活化对唑类进行直接芳基化获得了广泛的应用，可用于获取具有制药意义的有价值的小有机分子。在这方面，已经制备了带有溴离子 (5-7) 和六氟磷酸根阴离子 (8-10) 的空间变化的香豆素官能化咪唑盐，并将其用作 NHC 前体。这些盐已通过光谱和分析技术进行了表征。还使用单晶 XRD 技术研究了六氟磷酸盐 9 的结构。事实上，这些盐会产生卡宾，捕获 Cu(I)，在原位形成 Cu(I)-NHC 络合物，用于 1H-唑/苯胺和苯基/噻吩硼酸的 Chan-Evans-Lam C-N 偶联，从而产生以中等至优异的产率形成 N-芳基衍生物。构效关系研究表明，金属中心周围的空间体积有助于提高催化剂的Chan−Evans−Lam C–N 耦合潜力。
