    In an effort to identify novel anti-inflammatory compounds, a series of flavone derivatives were synthesized and biologically evaluated for their inhibitory effects on the production of nitric oxide (NO) and prostaglandin E2 (PGE2), representative pro-inflammatory mediators, in LPS-induced RAW 264.7 cells. Their structure-activity relationship was also investigated. In particular, we found that compound

    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.

    日期:2017.1.20
    method to chromenones and thiochromenones has been developed using a one-pot Friedel–Crafts acylation of alkynes with suitably substituted benzoyl chlorides. This unified approach to (thio)chromenones is readily applicable to aryl- and alkylalkynes where the stereochemically well-defined β-chlorovinyl ketone intermediates undergo distinctively different cyclization pathways. The ready availability

  • Synthetic approach to flavanones and flavones via ligand-free palladium(ii)-catalyzed conjugate addition of arylboronic acids to chromones
    作者:Donghee Kim、Kyungrok Ham、Sungwoo Hong
    DOI:10.1039/c2ob26061a
    日期:——
    The remarkable catalytic effects of Fe(OTf)3 in the context of the Pd(II)-catalyzed conjugate addition of arylboronic acids to chromones were observed to yield a variety of flavanones under mild conditions. The addition of catalytic amounts of DDQ and KNO2 to the reactions exclusively yielded flavone analogs. The reaction scope for the transformation was fairly broad, affording good yields of a wide range of flavanones and flavones, which are privileged structures in many biologically active compounds.
    在Pd(II)催化的芳基硼酸与色酮的共轭加成反应中,Fe(OTf)3显示出了显著的催化效应,能够在温和条件下合成各种黄酮。向反应中添加催化量的DDQ和KNO2则专门产生黄酮类似物。该转化的反应范围相当广泛,提供了良好的收率,合成了多种黄酮和黄酮类化合物,这些化合物在许多生物活性化合物中是具优势的结构。
