  .omega.-[(4-Phenyl-2-quinolyl)oxy]alkanoic acid derivatives: a new family of potent LTB4 antagonists

  摘要：

  A series of omega-[(4-phenyl-2-quinolyl)oxy]alkanoic acid derivatives was prepared which inhibited the binding of the leukotriene B4 to its receptors on guinea pig spleen membranes and on human polymorphonuclear leukocytes. A structure-activity relationship was investigated. The length of the carboxylic acid side chain was important for potent binding activity. The replacement of the oxygen atom at the beginning of the chain with other polar or nonpolar linking groups led to considerable loss of potency, indicating that the oxygen linking atom might be involved in the receptor recognition. Alpha-Substitution on the carboxylic acid side chain led to substantially more potent compounds. Substitution on the phenyl ring and on the quinoline ring was also evaluated.

• Palladium-Catalyzed Intramolecular Amidation of C(sp²)−H Bonds: Synthesis of 4-Aryl-2-quinolinones

  A catalytic synthetic approach for the synthesis of 2-quinolinone compounds through a Pd-catalyzed C(sp2)−H functionalization/intramolecular amidation sequence is described. The cyclization process efficiently proceeds in the presence of a catalytic amount of PdCl2 and Cu(OAc)2 under an O2 atmosphere, providing practical access to a range of variously substituted 4-aryl-2-quinolinones.

• The Heck Reaction of β-Arylacrylamides: An Approach to 4-Aryl-2-quinolones

  The Heck reaction of β-arylacrylamides with aryl iodides afforded the corresponding vinylic substitution products usually in high yields. The nature of β-substituents, aryl iodides and substituents at the nitrogen atom influences the stereochemical outcome. N,N-Dimethyl-β-arylacrylamides gave vinylic substitution products with higher stereoselectivity than the corresponding N-unsubstituted β-arylacrylamides. β-Arylacrylamides containing ortho-substituents led to the formation of only one stereoisomer. The procedure was used to prepare 4-aryl-2-quinolones from β-(o-bromophenyl)acrylamide through a sequential Heck reaction and copper-catalyzed cyclization process.

  β-芳基丙烯酰胺与芳基碘的Heck反应通常以高产率得到相应的烯基取代产物。β-取代基、芳基碘以及氮原子上的取代基对立体化学结果有影响。N,N-二甲基-β-芳基丙烯酰胺相较于相应的N-未取代β-芳基丙烯酰胺，其烯基取代产物具有更高的立体选择性。含邻位取代基的β-芳基丙烯酰胺生成单一立体异构体。通过连续的Heck反应和铜催化的环化过程，该方法被用于从β-(邻溴苯基)丙烯酰胺制备4-芳基-2-喹诺酮。

  A palladium‐catalyzed three‐component reaction between N‐tosylhydrazones, 2‐iodoanilines and atmospheric pressure CO2 was developed whereby a tandem carbene migration insertion/lactamization strategy afforded 4‐aryl‐2‐quinolinones in moderate to good yields. Notably, a wide range of functional groups were tolerated in this procedure. This protocol features the simultaneous formation of four novel bonds;

  A convenient one-pot method for the synthesis of 4-arylquinolin-2(1H)-ones and 4-arylcoumarins has been described. The successive Heck reaction on substituted 2-iodoaniline and 2-iodophenol catalyzed by a Pd/nickel ferrite catalyst followed by in situ cyclization was the key step. The scope of this methodology was extended to the synthesis of bioactive 3-alkenyl derivatives of 4-arylquinolin-2(1H)-ones.
