SRN1 Mechanism in Heteroaromatic Nucleophilic Substitution. Reactions Involving Certain Dihalogenated ?-Deficient Nitrogen Heterocycles

Photostimulated reactions of 2,6-,2,3-, 3,5-, and 2,5-dihalopyridines (1a-e) with pinacolone potassium enolate (2) in liquid NH3 lead to facile replacement of both halogens via a modified SRN1 mechanism, which does not involve intermediate formation of monosubstitution products.The potassium salts of phenylacetonitrile (12a) and alpha-ethylphenylacetonitrile (12b) react with 2,6-dibromopyridine (1a) under similar conditions to afford a mixture of mono- and disubstituted products via a related SRN1 process. 4,7-Dichloroquinoline (16) undergoes radical-chain displacement of chloride from C4 with enolate 2. 2,6-Dichloropyrazine (18) and 2,3-dichloropyrazine (20) also undergo monosubstitution with 2 and diisopropyl ketone potassium enolate (22), but these reactions appear to be mainly addition-elimination (SNAr) processes.Treatment of 3,6-dichloropyridazine (27) with 22 results in addition of 22 to C4 of the substrate.Photoassisted reaction of 2,4-dichloropyrimidine (31) with 12a leads to exclusive chloride displacement from C4 via the SRN1 mechanism.

A General Synthesis of Substituted Indoles from Cyclic Enol Ethers and Enol Lactones

(Equation presented) A general method was developed for the one-pot synthesis of highly functionalized indoles from simple, commercially available aryl hydrazines and cyclic enol ethers. Enol lactones were also used as substrates, affording substituted indole acetic acid or indole propionic acid derivatives. This procedure affords 2,3-disubstituted indoles as single regioisomers from the appropriately substituted enol ether or enol lactone. This method was highlighted in the efficient synthesis of the antimigraine drug sumitriptan and the antiinflammatory drug indomethacin.

Novel 5-hydroxytryptamine (5-HT3) receptor antagonists. II. Synthesis and structure-activity relationships of 4,5,6,7-tetrahydro-1H-benzimidazole derivatives

A novel series of 4,5,6,7-tetrahydro-1H-benzimidazole derivatives 4, 5, 6 and 7 was prepared and evaluated for activities as 5-hydroxytryptamine (5- HT3) receptor antagonists which may be useful for the treatment of irritable bowel syndrome (IBS) as well as nausea and vomiting associated with cancer chemotherapy. These compounds were designed by modifying the aromatic- carbonyl part of N-(2-methoxyphenyl)-4,5,6,7-tetrahydro-1H-5- benzimidazolylcarboxamide 3, leaving the imidazole moiety unchanged as the amine part. The indole derivatives 7d, g, h and indolizine derivatives 7k, 1 were found to be highly potent on the von Bezold-Jarisch (B.J.) reflex test with ID50 values of below 0.1 mug/kg, and the indoline derivative 6c, indole derivatives 7a, d, g, benzofurane derivative 7j and indolizine derivative 7k were observed to be very potent on the colonic contraction with IC50 values of below 0.1 muM. In particular, 71 was the most potent on the B.J. reflex (ID50 = 0.018 mug/kg), approximately 200 and 50 times more potent than ondansetron 1 and granisetron 2, and 7k was the most potent on the colonic contraction (IC50 = 0.011 muM), approximately 70 and 6 times more potent than 1 and 2, respectively.

Synthesis and biological evaluation of new heteroaryl carboxylic acid derivatives as anti-inflammatory-analgesic agents

A series of nicotinic acid derivatives structurally related to niflumic acid and certain pyridazine-containing compounds have been synthesized and characterized by analytical and spectral data. All compounds were screened for their potential analgesic and anti-inflammatory activities. The compounds which displayed analgesic and anti-inflammatory activities were tested for ulcerogenicity and screened for in vivo inhibition of certain inflammatory cytokines such as tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), and cyclooxygenase-2 (COX-2). Compounds 1c, 2a, 2b, and 5a have shown potent analgesic and anti-inflammatory activities.
