The present research work involved the reaction of 2,3-dihydro-1,4-benzodioxin-6-amine (1) and benzenesulfonyl chloride (2) under dynamic pH control at 10 using aqueous Na2CO3. This reaction yielded 2,3-dihydro-1,4-benzodioxin-6-yl)benzenesulfonamide (3), which was further substituted at N-position with various alkyl/aryl halides (4a ? 4m) in N,N-dimethylformamide and catalytic amount of lithium hydride to obtain N-substituted (2,3-dihydro-1,4-benzodioxin-6-yl)benzenesulfonamides (5a ? 5m). The projected structures of the synthesized derivatives were confirmed using various spectral techniques (IR, 1H NMR and EIMS). The synthesized derivatives were screened for antibacterial potential and inhibitory activity against lipoxygenase enzyme.

Electric Literature of 70918-54-6, Irreversible inhibitors are therefore the equivalent of poisons in heterogeneous catalysis.Enzyme inhibitors cause a decrease rate of an enzyme-catalyzed reaction to a specific portion of an enzyme and thus slowing a reaction . In an article, 70918-54-6, molcular formula is C9H8O4, introducing its new discovery.

Two series of novel 2,3-dihydrobenzo[b][1,4]dioxin-containing 4,5-dihydro-1H-pyrazole derivatives C1-C15 and D1-D15 have been synthesized and evaluated for their B-Raf inhibitory and anti-proliferation activities. Compound C14 ((3-(4-bromophenyl)-5-(2-fluorophenyl)-4,5-dihydro-1H-pyrazol-1-yl)(2,3- dihydrobenzo[b][1,4]dioxin-6-yl)methanone) showed the most potent biological activity against B-RafV600E (IC50 = 0.11 muM) and WM266.4 human melanoma cell line (GI50 = 0.58 muM), being comparable with the positive control Erlotinib and more potent than our previous best compound, while D10 ((2,3-dihydrobenzo[b][1,4]dioxin-2-yl)(5-(3- fluorophenyl)-3-phenyl-4,5-dihydro-1H-pyrazol-1-yl)methanone) performed the best in the D series (IC50 = 1.70 muM; GI50 = 1.45 muM). The docking simulation was performed to analyze the probable binding models and poses and the QSAR model was built for reasonable design of B-Raf inhibitors in future. The introduction of 2,3-dihydrobenzo[b][1,4]dioxin structure reinforced the combination of our compounds and the receptor, resulting in progress of bioactivity.

The aim of the present research work was to investigate the enzyme inhibitory potential of some new sulfonamides having benzodioxane and acetamide moieties. The synthesis was started by the reaction of N-2,3-dihydrobenzo[1,4]-dioxin-6-amine (1) with 4-methylbenzenesulfonyl chloride (2) in the presence of 10% aqueous Na2CO3 to yield N-(2,3-dihydrobenzo[1,4]-dioxin-6-yl)-4-methylbenzenesulfonamide (3), which was then reacted with 2-bromo-N-(un/substituted-phenyl)acetamides (6a-l) in DMF and lithium hydride as a base to afford various 2-{2,3-dihydro-1,4-benzodioxin-6-yl[(4-methylphenyl)sulfonyl] amino}-N-(un/substituted-phenyl)acetamides (7a-l). All the synthesized compounds were characterized by their IR and 1H-NMR spectral data along with CHN analysis data. The enzyme inhibitory activities of these compounds were tested against a-glucosidase and acetylcholinesterase (AChE). Most of the compounds exhibited substantial inhibitory activity against yeast a-glucosidase and weak against AChE. The in silico molecular docking results were also consistent with in vitro enzyme inhibition data.

A simple and straightforward method for facile access to coumarin-fused dihydroquinolines (4) has been developed using the microwave-assisted multicomponent reactions of 4-hydroxycoumarin, aldehydes and aromatic amines in water catalyzed by bismuth triflate. Under solvent-free and conventional heating conditions, the same combination provided the corresponding coumarin-fused quinolines (5). An alternative and rapid method for the conversion of (4) to (5) with very good yields was also developed using N-bromosuccinamide. Single-crystal X-ray crystallographic analysis of one of the products (4q) showed that the products are regioselective and that the reactions proceed via 1,2-addition followed by 6pi-electrocyclization instead of a Skraup-Doebner-von Miller type reaction. Substituted quinoline carboxylic acid derivatives (7) were synthesized selectively from (4) by ring opening of the coumarin moiety followed by aromatization using NaOH/DMSO under reflux conditions. Considering the presence of the polycyclic conjugated structure of the synthesized compounds 4 and 5 with the coumarin moiety, preliminary photophysical studies were carried out and promising quantum yields were observed along with a maximum quantum yield (of = 0.65) for 4j.

Pyrrolo[1,2-a]quinoxalines were synthesized through a three-component reaction of 2-alkoxy-2,3-dihydrofuran, o-phenylenediamine and ketone. This reaction was performed in nitromethane by using boron trifluoride etherate as catalyst. Mechanism of this reaction involves the following two steps: (i) a condensation reaction of the dihydrofuran with o-phenylenediamine, which produced a N-(2-aminophenyl)pyrrole derivative that can act as a 1,5-bisnucleophile, and (ii) an intramolecular Mannich-type reaction of the bisnucleophile and ketone to produce the pyrrolo[1,2-a]quinoxaline derivative.
