    摘要:
    通过使用芳基肼作为芳基自由基源和空气作为氧化剂,可以在碱存在下实现喹啉-4-酮的无过渡金属C-3-芳基化。该反应在室温下平稳进行,不需要任何预官能化和喹啉-4-酮的N-保护。该方法的实用性在喹啉-喹诺酮杂化物以及6-芳基-苯并呋喃[3,2- c ]喹啉支架的合成中得到了进一步证明。

    Herein, a novel and efficient intermolecular cyclization of 2-aminoacetophenones with aldehydes was developed for the synthesis of 2-aryl-4-quinolones through C–C and C–N bond formation. Mild conditions, good functional group tolerance, and substrates without prefunctionalization make this protocol practical, and this strategy will stimulate keen interest in fields of chemistry and biology.

  • Ruthenium(II) Catalyzed Regiospecific C–H/O–H Annulations of Directing Arenes via Weak Coordination
    作者:Arghya Banerjee、Sourav Kumar Santra、Prakash Ranjan Mohanta、Bhisma K. Patel
    DOI:10.1021/acs.orglett.5b02967
    日期:2015.11.20
    Ruthenium(II) catalyzed oxidative CH/OH annulations have been demonstrated using two different directing arenes viz. 2-arylquinolinone and 2-arylbenzoxazinone with internal alkynes. Regiospecific annulations have been observed for both directing arenes via the assistance of weaker carbonyl oxygen in the presence of a stronger nitrogen-directing site. In this substrate-controlled convergent protocol the weaker directing group dictates the annulation path.
  • Evaluation of synthetic acridones and 4-quinolinones as potent inhibitors of cathepsins L and V

    Cathepsins, also known as lysosomal cysteine peptidases, are members of the papain-like peptidase family, involved in different physiological processes. In addition, cathepsins are implicated in many pathological conditions. This report describes the synthesis and evaluation of a series of N-arylanthranilic acids, acridones, and 4-quinolinones as inhibitors of cathepsins V and L The kinetics revealed that compounds of the classes of acridones are reversible competitive inhibitors of the target enzyme with affinities in the low micromolar range. They represent promising lead candidates for the discovery of novel competitive cathepsin inhibitors with enhanced selectivity and potency. On the other hand, 4-quinolinones were noncompetitive inhibitors and N-arylanthranilic acids were uncompetitive inhibitors. (C) 2012 Elsevier Masson SAS. All rights reserved.
