- FLUOROBORON COMPOUND HAVING AROMATIC RING OR SALT THEREOF, AND PROCESS FOR PRODUCTION OF COMPOUND HAVING CYCLIC ETHER-FUSED AROMATIC RING BY USING THE SAME
-
Provided is a fluoroboron compound which is highly safe and stable and is capable of forming a cyclic ether-fused ring by the intramolecular alkoxymethylation reaction, or a salt thereof. The compound can be synthesized by the intramolecular alkoxymethylation reaction of a fluoroboron compound represented by the formula (I) or a salt thereof in the presence of a metal catalyst. (wherein the moiety represented by the formula represents an aromatic ring; L represents a substituent such as a halogen atom; R represents a substituted or unsubstituted alkylene group having 1 or 2 carbon atoms; and M represents an alkali metal cation or the like, with the proviso that L and -R-OCH2BF3M are respectively located on contiguous carbon atoms on the aromatic ring, or in the case of a fused aromatic ring, on two carbon atoms adjacent to one carbon at the fused position).

- Imidazo pyridine-2-ones and pharmaceutical compositions and methods of treatment utilizing same
-
1,3-Dihydroimidazo[4,5-b]pyridin-2-ones and corresponding thiones have utility as analgesic, antipyretic and antiinflammatory agents. They are generally prepared by treatment of a 2,3-diaminopyridine with phosgene or thiosphosgene followed by further substitution if desired.

- Synthesis and analgesic activity of 1,3-dihydro-3-(substituted phenyl)imidazo[4,5-6]pyridin-2-ones and 3-(substituted phenyl)-1,2,3-triazolo[4,5-b]pyridines
-
In a study of nonsteroidal antiinflammatory and analgesic agents, a series of 1,3-dihydro-3-(substituted phenyl)imidazo[4,5-b]pyridin-2-ones and 3-(substituted phenyl)triazolo[4,5-b]pyridines was prepared. Many of the imidazolones were alkylated on the free nitrogen. In a modified Randall-Selitto analgesic assay, the pain thresholds of both the inflamed and normal foot were elevated. This is not commonly observed with nonsteroidal antiinflammatory agents. The most active compounds were 1,3-dihydro-3-[3,4-(methylenedioxy)phenyl]imidazo[4,5-b]pyridin-2-one (I-15) and its N-allyl (I-21) and N-isopropyl (I-121) derivatives. In the triazole series the 3-(2-fluoro- and 2,4-difluorophenyl)triazolo[4,5-b]pyridines (T-1 and T-8) were the best. The imidazole compounds were somewhat superior in analgesic activity to codeine and d-propoxyphene without showing any narcotic characteristics. Some of the compounds also possessed activity against carrageenan-induced foot edema in the rat, so these compounds represent a new class of nonnarcotic analgesic antiinflammatories, capable of producing a greater degree of analgesia than that obtainable with other nonsteroidal antiinflammatory agents.
