  Synthesis and Anti-HCV Activity of 4-Hydroxyamino α-Pyranone Carboxamide Analogues

  摘要：

  High genetic variability in hepatitis C virus (HCV), emergence of drug resistant viruses and side effects demand the requirement for development of new scaffolds to show an alternate mechanism. Herein, we report discovery of new scaffold I based on 4-hydroxyamino alpha-pyranone carboxamide as promising anti-HCV agents. A comprehensive structure activity relationship (SAR) was explored with several newly synthesized compounds. In all promising compounds (17-19, 21-22, 24-25, and 49) with EC50 ranging 0.15 to 0.40 mu M, the aryl group at C-6 position of alpha-pyranone were unsubstituted. In particular, 25 demonstrated potential anti-HCV activity with EC50 of 0.18 mu M in cell based HCV replicon system with lower cytotoxicity (CC50 > 20 mu M) and provided a new scaffold for anti-HCV drug development. Further investigations, including biochemical characterization, are yet to be performed to elucidate its possible mode of action.

• Transition‐Metal‐Promoted Direct C−H Cyanoalkylation and Cyanoalkoxylation of Internal Alkenes <i>via</i> Radical C−C Bond Cleavage of Cycloketone Oxime Esters

  d alkyl‐Heck‐type cross‐coupling of olefinic C−H bonds has been a challenge in the C−H activation area. Herein, we report FeCl3‐promoted efficient direct C−H cyanoalkylation of internal alkenes, that is, ketene dithioacetals, with cycloketone oxime esters via radical C−C bond cleavage under the redox‐neutral conditions. With CuCl2 as the catalyst under a dioxygen atmosphere direct C−H cyanoalkoxylation

  烯烃CH键的过渡金属催化的烷基-Heck型交叉偶联一直是CH活化领域的一个挑战。在本文中，我们报道了FeCl 3促进了内部烯烃（即烯酮二硫缩醛）与环酮肟酯的有效直接C-H氰基烷基化反应，在氧化还原-中性条件下通过自由基C-C键裂解。以CuCl 2为催化剂，在双氧气氛下，可将相同的内部烯烃直接进行CH氰基烷氧基化反应。氰基烷基化的四取代烯烃产物可以多样化地转化为氰基烷基官能化的N和S杂环化合物。机理研究表明，这些CH氰基烷基化和氰基烷氧基化反应是通过自由基途径进行的。

  These precursors are easily accessible from aryl methyl ketones. Various functional groups like alkyl, aryl, nitrile, amine, aroyl and thiomethyl can be directly installed to the benzene ring. The one-pot approach for the construction of thiomethylated-benzene nucleus was also developed. The structure of the synthesized compound was confirmed by X-ray crystallography.
