  • Palladium‐Catalyzed Chlorocarbonylation of Aryl (Pseudo)Halides Through In Situ Generation of Carbon Monoxide
    作者:Philip Boehm、Sven Roediger、Alessandro Bismuto、Bill Morandi

    日期:2020.10.5
    efficient palladiumcatalyzed chlorocarbonylation of aryl (pseudo)halides that gives access to a wide range of carboxylic acid derivatives has been developed. The use of butyryl chloride as a combined CO and Cl source eludes the need for toxic, gaseous carbon monoxide, thus facilitating the synthesis of high‐value products from readily available aryl (pseudo)halides. The combination of palladium(0), Xantphos

    A series of nineteen 2-aryl-4H-chromen-4-one derivatives 2a-2s were synthesized and evaluated for their antiviral activity against Chikungunya virus (LR2006_OPY1) in Vero cell culture by CPE reduction assay. Three compounds 2a, 2b and 2g, were found to be active at concentration of (IC50) 0.44 M, 0.45 M and 2.02 M, respectively. Compounds having heterocyclic ring 2a and 2b at the 2nd position of the chromenone were found to be potent inhibitor of ChikV. Cytotoxicity studies were performed using Vero cell culture, compounds 2a and 2b exhibited SI of 100. Molecular docking simulation has been carried out to understand the possible mechanism of action.

  • Pd–carbene catalyzed carbonylation reactions of aryl iodides
    作者:Liqin Xue、Lijun Shi、Yuan Han、Chungu Xia、Han Vinh Huynh、Fuwei Li
    DOI:10.1039/c1dt10433k
    日期:——
    A series of carbene complexes [PdBr2(iPr2-bimy)L] (C2–C13) with different types of co-ligands (L) have been tested for their catalytic activities in the carbonylative annulation of 2-iodophenol with phenylacetylene in DMF to afford the respective flavone 2a. Complex C12 with an N-phenylimidazole co-ligand showed the best activity and also afforded high yields when the substrate scope was extended to other aryl or pyridyl acetylenes. In addition, catalyst C12 was also efficient in the carbonylative annulation of 2-iodoaniline with acid chlorides giving the desirable 2-substituted 4H-3,1-benzoxazin-4-ones (4) in good yields. Additionally, this Pd–NHC complex also proved to be a very efficient catalyst for the hydroxycarbonylation of iodobenzene derivatives at low catalyst loading and under low CO pressure. These results demonstrate the versatility and efficiency of this phosphine-free Pd(II)–NHC complex in different types of carbonylations of aryl iodides under mild conditions.
    一系列含有不同类型配体(L)的卡宾配合物[PdBr2(iPr2-bimy)L](C2至C13)被测试其在二甲基甲酰胺(DMF)中催化2-碘苯酚与苯乙炔进行羰基化环化反应的活性,以制备相应的黄酮2a。含有N-苯基咪唑配体的配合物C12显示出最佳活性,并且在将底物范围扩展到其他芳基或吡啶乙炔时也能获得高产率。此外,催化剂C12在催化2-碘苯胺与酰氯进行羰基化环化反应中也表现高效,以良好产率得到了理想的2-取代的4H-3,1-苯并噁嗪-4-酮(4)。此外,这种Pd-NHC配合物在对碘苯衍生物进行羟基羰基化反应中也证明是一种非常高效的催化剂,催化剂用量低且在低CO压力下。这些结果展示了这种不含膦的Pd(II)-NHC配合物在温和条件下对芳基碘化物进行不同类型羰基化反应的多功能性和高效性。
