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.

article reports the first example of a 2-pyridone accelerated non-directed C-H cyanation with an arene as the limiting reagent. This protocol is compatible with a broad scope of arenes, including advanced intermediates, drug molecules, and natural products. A kinetic isotope experiment (kH /kD =4.40) indicates that the C-H bond cleavage is the rate-limiting step. Also, the reaction is readily scalable

Pd(OAc)<sub>2</sub>-Catalyzed Alkoxylation of Arylnitriles via sp<sup>2</sup> C–H Bond Activation Using Cyano as the Directing Group

A Pd(OAc)(2)-catalyzed ortho-alkoxylation of arylnitrile was described. Using cyano as a directing group, the aromatic C-H bond can be functionalized efficiently to generate ortho-alkoxylated arylnitrile derivatives with moderate yields. The optimal reaction conditions were identified after examining various factors such as oxidant, solvent, and reaction temperature. The method was compatible to the arylnitriles with either electron-withdrawing or electron-donating groups.
