  Chromenones as potent bradykinin B1 antagonists

  摘要：

  A series of fused 6,6-bicyclic chromenones was investigated for activity against the bradykinin B1 receptor. SAR studies based on a pharmacophore model revealed compounds with high affinity for both human and rabbit B1. These compounds demonstrated favorable pharmacokinetic properties and 5-chlorochromenone 15 was efficacious in a carrageenan-induced mechanical hyperalgesia model for chronic pain.

  catalysis has been developed to achieve oxidative C–H chlorination of aromatic compounds using NaCl as the chlorine source and Na2S2O8 as the oxidant. The reactions occur at room temperature and exhibit exclusive selectivity for C(sp2)–H bonds over C(sp3)–H bonds. The method has been used for the chlorination of a diverse set of substrates, including the expedited synthesis of key intermediates to bioactive

  deals with conformational behaviour of 2-methoxy-2′-hydroxythiobenzanilides. The CS-NH group of these compounds preferentially adopts the Z-conformation. Entropy favours the Z-conformer over the E-conformer, whereas enthalpy slightly favours the E-conformer over the Z-conformer. The rotational barrier about the CS-NH bond was determined to be (81.5±0.4) kJ/mol. No significant rotational barrier was found

  for a faster, safer protocol for the direct synthesis of 5-aryltetrazoles from aryl nitriles in the presence of sodium azide and an amine hydrochloride salt led to the discovery of a buffered system comprised of BnNH2, BnNH2·HCl, and NaN3. After optimization of reaction conditions and a thorough investigation of reaction safety, the procedure was demonstrated for the synthesis of several hundred grams

  日期：2011.8.19

  A palladium-catalyzed decarboxylative cross-coupling of potassium 2- and 4-nitrophenyl acetates with aryl chlorides and bromides has been developed. Because the nitro group can be readily converted to many other functional groups, the new reaction provides a useful method for the preparation of diverse 1,1-diaryl methanes and their derivatives.
