  Synthesis of symmetrically substituted 3,3-dibenzyl-4-hydroxy-3,4-dihydro-1H-quinolin-2-ones, as novel quinoline derivatives with antibacterial activity

  摘要：

  A novel series of symmetrically substituted 3,3-dibenzy1-4-hydroxy-3,4-dihydro-1H-quinolin-2-ones was synthesized and tested as antimicrobials. The minimum inhibitory concentration (MIC) values of the most active heterocycles were slightly higher than those exhibited by levofloxacin, employed as comparator. Structural factors affecting the activity were explored along three diversification points, including the substituents of the aromatic rings of the 3-benzyl moieties, as well as the functionalization of both, the homocyclic ring of the heterocycle and the quinolonic nitrogen atom. 6-Chloro and 3,3-bis(4'-chlorobenzyl) derivatives showed the lower MIC values. Optimally substituted heterocycles were synthesized, which exhibited enhanced activity. (C) 2014 Elsevier Masson SAS. All rights reserved.

  unprecedented use of 2,2,2-trifluoroethanol as reaction solvent provided a facile and convenient access to symmetrically 3,3-disubstitued quinoline-2,4-diones in moderate to excellent yields and high regioselectivity, by reaction of 4-hydroxy-2-quinolones with electrophiles like methyl iodide, as well as benzyl and allyl bromides in the presence of K2CO3. Silver (I) oxide is required to increase the yield of

  通过2,2,2-三氟乙醇作为反应溶剂的空前使用，通过4-羟基-苯酚的反应，以中等至极好的收率和高区域选择性提供了一种方便且便捷的途径，可对称地获得3,3-二取代的喹啉-2,4-二酮。在K 2 CO 3存在下，具有亲电试剂的2-喹诺酮类化合物，如甲基碘，以及苄基和烯丙基溴。需要氧化银（I）以增加甲基化的产率。
