  A versatile and efficient synthesis of 3-aroyl-1,4-dihydroquinolin-4-ones

  摘要：

  A versatile and efficient method for preparation of 3-aroyl-4-quinolones is described. The procedure involved a Michael-type addition of methyl anthranylate with various beta-ketonic enol ethers followed by based promoted cyclisation. Different quinolones have been obtained. The ring closure is facilitated by heating at reflux in diphenyl ether leading to increase the rate of the cyclisation. (C) 2004 Elsevier Ltd. All rights reserved.

• Pharmacomodulations around the 4-Oxo-1,4-dihydroquinoline-3-carboxamides, a Class of Potent CB₂-Selective Cannabinoid Receptor Ligands:  Consequences in Receptor Affinity and Functionality

  CB2 receptor selective ligands are becoming increasingly attractive drugs due to the potential role of this receptor in several physiopathological processes. Thus, the development of our previously described series of 4-oxo- 1,4-dihydroquinoline-3-carboxamides was pursued with the aim to further characterize the structure-affinity and structure - functionality relationships of these derivatives. The influence of the side chain was investigated by synthesizing compounds bearing various carboxamido and keto substituents. On the other hand, the role of the quinoline central scaffold was studied by synthesizing several 6-, 7-, or 8-chloro-4oxo-1,4-dihydroquinolines, as well as 4-oxo-1,4-dihydronaphthyridine and 4-oxo-1,4-dihydrocinnoline derivatives. The effect of these modifications on the affinity and functionality at the CB2 receptor was studied and allowed for the characterization of new selective CB2 receptor ligands.
