Palladium-Catalyzed C(sp2)–H Pyridocarbonylation of N-Aryl-2-aminopyridines: Dual Function of the Pyridyl Moiety
摘要:
An efficient synthesis of 11H-pyrido[2,1-b]-quinazolin-11-one through palladium-catalyzed C(sp(2))-H pyridocarbonylation of N-aryl-2-aminopyridines has been developed. The pyridyl group acts as an intramolecular nucleophile for the first time in C-H carbonylation reactions.
The present invention relates to the use of vanilloid receptor (VR) antagonists, and more particularly vanilloid receptor 1 (VR1) antagonist, as analgesics in the treatment and/or prohylaxis of cnidaria envenomations.
