A metal‐free synthesis of a range of 4‐aryl‐2‐quinolone derivatives has been developed which utilizes an iodine‐mediated intramolecular C−H amidation of 3,3‐diarylacryl amides as the key step. Electron‐withdrawing or ‐donating substituents in either of the aryl rings display marginal influence on the course of the reaction. However, the presence of the diarylalkene moiety has been found to be crucial

The vanilloid receptor-1 (TRPV1 or VR1) is a member of the transient receptor potential (TRP) family of ion channels and plays a role in regulating the function of sensory nerves. A growing body of evidence demonstrates the therapeutic potential of TRPV1 modulators: particularly in the management of pain. As a result of our screening efforts, we identified (E)-3-(4-tert-butylphenyl)-N-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)acrylamide (1): an antagonist that blocks the capsaicin-induced and pH-induced uptake of Ca-45(2+) in TRPV1-expressing Chinese hamster ovary cells with IC50 values of 17 +/- 5 and 150 +/- 80 nM, respectively. In this report.. we describe the synthesis and structure-activity relationship of a series of N-aryl cinnamides, the most potent of which (49a and 49b) exhibit good oral bioavailability in rats (F-oral = 39% and 17%. respectively).
