halogen bond-assisted electron-catalyzed iodination of heteroarenes has been developed for the first time under atom economic condition at room temperature. The iodination is successful with just 0.55 equiv of iodine and 0.50 equiv of peroxide. The kinetic study indicates that the reaction is elusive in the absence of a halogen bond between the substrate and iodine. The formation of a halogen bond, its
Compounds of Formula I are useful as antagonists of TRPM8. Such compounds are useful in treating a number of TRPM8 mediated disorders and conditions and may be used to prepare medicaments and pharmaceutical compositions useful for treating such disorders and conditions. Examples of such disorders include, but are not limited to, migraines and neuropathic pain. Compounds of Formula I have the following structure:

A novel and convenient method has been developed for the regioselective iodination of quinolines at their C3 position under metal-free conditions. Iodinated quinolines, which are popular building blocks in organic and medicinal chemistry, can be prepared in gram quantities and good yields using this method and further derivatized to give increasingly complex compounds. Preliminary mechanistic studies have shown that this reaction most likely occurs via a radical intermediate.

3-Haloquinolines can be functionalized via a palladium-catalyzed desulfitative coupling of arylsulfinates. This method tolerates substitution upon the aromatic ring and shows good selectivity toward variously substituted aromatic rings. (C) 2013 Elsevier Ltd. All rights reserved.
