Novel and highly potent 5-HT3 receptor agonists based on a pyrroloquinoxaline structure

The synthesis and the biological evaluation of a series of novel pyrroloquinoxaline derivatives are described. In binding studies several compounds proved to be potent and selective 5-HT3 receptor ligands. The most active pyrroloquinoxalines, 11d and 11e, showed a subnanomolar affinity for 5-HT3 receptor and were able to functionally discriminate the central and peripheral 5-HT3 receptors, being agonists and antagonists, respectively. In functional studies ([14C]-guanidinium accumulation test in NG 108-15 cells, in vitro) most of the synthesized compounds showed clear-cut 5-HT3 agonist properties. In in vivo studies on the von Bezold-Jarisch reflex test (a peripheral interaction model) the behavior of the tested compounds ranged from agonist to antagonist, while clear agonist properties were obtained with 12a on cortical acetylcholine release in freely moving rats. Pharmacokinetic studies with 11e and 12c indicate that the compounds easily cross the blood- brain barrier (BBB) after systemic administration with a brain/plasma ratio of 17.5 and 37.5, respectively. Thus compounds 11e and 12c represent the most potent central 5-HT3 agonists identified to date that are able to cross the blood-brain barrier.

Solvent-free reaction using phosphonium salts: Chlorination of hydroxyheteroaromatics and dehydration of primary amides

Solvent-free chlorination of heteroaromatics using the phosphonium salt, prepared by reaction of triphenylphosphine with N-chlorosuccinimide, was accomplished by microwave-irradiation or heating to give the corresponding chloroheteroaromatics. Similarly, primary amides was converted into nitriles by this method.{A figure is presented}.

Studies on the synthesis of 2-phenylsulphonyl-3-styrylquinoxalines

o-Phenylenediamine 1 is condensed with pyruvic acid or sodium pyruvate to yield 3-methylbenzo-1H-dihydropyrazine-2-one 2. The latter on condensation with aromatic aldehydes give 3-styrylquinoxaline-1H-2-one 3. Reaction of 3 with POCl3 in the presence of catalytic amount of DMF yields 2-chloro-3-styrylquinoxaline 4, which on reaction with thiophenol in the presence of triethylamine in methanol gives 2-phenylthio-3-styrylquinoxaline 5. Oxidation of 5 with H2O2 in the presence of acetic anhydride affords 2-phenylsulphonyl-3-styrylquinoxaline 6. 6 has also been prepared directly from 4 by reaction with sodium benzenesulphinate under phase transfer conditions.

Relay Catalysis of Bismuth Trichloride and Byproduct Hydrogen Bromide Enables the Synthesis of Carbazole and Benzo[alpha]carbazoles from Indoles and alpha-Bromoacetaldehyde Acetals

Benzo[alpha]carbazoles were synthesized from 2-phenylindoles and alpha-bromoacetaldehyde using bismuth trichloride as a catalyst. The reaction was triggered by a bismuth trichloride-catalyzed Friedel-Crafts alkylation of these two precursors, which provided a tryptaldehyde intermediate that underwent intramolecular olefination to form the final product. Interestingly, the HBr byproduct generated in the upstream step of the reaction catalyzed the following downstream reaction steps, thus creating a byproduct-participated relay catalytic process. Motivated by this mechanism, we developed a three-component reaction of indole, alpha-bromoacetaldehyde acetal, and 1,3-dicarbonyl compounds. This study offers a straightforward method for synthesizing substituted carbazoles. (Figure presented.).
