Crystallization-based resolution of 1,4-benzodioxane-2-carboxylic acid enantiomers via diastereomeric 1-phenylethylamides

Unlike the diastereomeric 1-phenylethylammonium salts, the diastereomeric N-1-phenylethylamides of (S)- and (R)-1,4-benzodioxane-2-carboxylic acid show significant differences in fusibility and solubility so as to be efficiently resolved by precipitation of the less soluble diastereomer (>98% de), while chromatographic purification of the unprecipitated fraction affords the more soluble one (>99% de). Overall, 95% of the former and 80% of the latter are recovered. The hydrolysis of the two resolved amides provides the two acid enantiomers and the resolving amine in quantitative yield and with unchanged stereoisomeric purity.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 3663-79-4, you can also check out more blogs about3663-79-4

Aerobic oxidative alpha-iodination of carbonyl compounds using molecular iodine activated by a nitrate-based catalytic system

The novel reaction system comprising air/NH4NO3(cat.)/I2/H2SO4(cat.)is introduced as a simple, safe, cheap, efficient, and regioselective mediator for direct aerobic oxidative alpha-iodination of aryl, heteroaryl, alkyl, and cycloalkyl methyl ketones. The reaction system enabled the moderate to quantitative regioselective iodination of a large range of different methyl ketone derivatives including those bearing oxidizable heteroatom (S, N) substituents. Several activated aromatic compounds were also efficiently and selectively iodinated. The practical applicability of the presented reaction system was shown on 20 mmol scale under ambient pressure and 100% conversion of substrate was achieved.

Direct Decarboxylative Allylation and Arylation of Aliphatic Carboxylic Acids Using Flavin-Mediated Photoredox Catalysis

We describe herein a direct decarboxylative allylation of aliphatic carboxylic acids with allylsulfones using visible light and riboflavin tetraacetate (RFTA) as photocatalyst. The reaction proceeds at room temperature tolerating a wide range of functionalities, avoiding the use of external bases or additives. Mechanistic studies support that alkyl radicals are involved in the reaction and that a true photocatalytic cycle is operating. It is proposed that the carboxylic acid is deprotonated by [RFTA]¡¤?, and the corresponding carboxylate acts as a reductive quencher of RFTA*, which after decarboxylation produces the alkyl radical. The methodology was adapted to prepare benzothiazoles substituted at C2, by reacting some carboxylic acids with 2-(phenylsulfonyl)benzothiazole. The number of carboxylic acids suitable for this arylation was lower than for the allylation and this different reactivity was briefly commented.

Design, synthesis and evaluation of 2-aminothiazole derivatives as sphingosine kinase inhibitors

Sphingosine kinases (SphK1, SphK2) are main regulators of sphingosine-1-phosphate (S1P), which is a pleiotropic lipid mediator involved in numerous physiological and pathophysiological functions. SphKs are targets for novel anti-cancer and anti-inflammatory agents that can promote cell apoptosis and modulate autoimmune diseases. Herein, we describe the design, synthesis and evaluation of an aminothiazole class of SphK inhibitors. Potent inhibitors have been discovered through a series of modifications using the known SKI-II scaffold to define structure-activity relationships. We identified N-(4-methylthiazol-2-yl)-(2,4?-bithiazol)-2?-amine (24, ST-1803; IC50values: 7.3 muM (SphK1), 6.5 muM (SphK2)) as a promising candidate for further in vivo investigations and structural development.

Synthesis of N-Substituted (2,3-Dihydro-1,4-Benzodioxin-6-YL)Benzenesulfonamide Derivatives as Potent Antibacterial Agents and Moderate Enzyme Inhibitors

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.

Design, synthesis and characterization of potent microtubule inhibitors with dual anti-proliferative and anti-angiogenic activities

Microtubule has been an important target for anticancer drug development. Here we report the discovery and characterization of a series of fused 4-aryl-4H-chromene-based derivatives as highly potent microtubule inhibitors. Among a total of 37 derivatives synthesized, 23 exhibited strong in vitro anti-proliferative activities against A375 human melanoma cells. The relationship between the biological activities of these microtubule inhibitors and their chemical structure variations was analyzed. Studies of compounds 27a, 19a and 9a in parallel with colchicine as the positive control compound in a panel of biological assays revealed that these compounds blocked cell cycle progression, increased apoptosis, and inhibited HUVEC capillary tube formation at low nanomolar concentrations. The most potent compound 27a was also tested in eight additional cancer cell lines besides A375 cells and two non-cancer cells and showed potent and selective activity on these cancer cells. To understand the molecular and structure mechanism of action of these compounds, tubulin polymerization and molecular docking studies were carried out for 27a as the representative. The results were consistent with the mechanism by which 27a interacts with the colchicine binding site on tubulin and disrupts tubulin polymerization. With potent dual actions of microtubule destabilization and vascular disruption described above, this small molecule can serve as a valuable research probe of the function and role of microtubules in human diseases and promising lead for developing new therapeutic agents.

Synthesis of new 3-phenylquinazolin-4(3H)-one derivatives as potent antibacterial agents effective against methicillin- and vancomycin-resistant Staphylococcus aureus (MRSA and VRSA)

Occurrence of infections due to the drug resistant Staphylococcus aureus is on rise necessitating the need for rapid development of new antibacterial agents. In our present work, a series of new 3-phenylquinazolin-4(3H)-one derivatives were designed, synthesized and evaluated for their antibacterial activity against ESKAP (E. coli, S. aureus, K. pneumoniae, A. baumannii, P. aeroginosa) pathogen panel and pathogenic mycobacterial strains. The study revealed that compounds 4a, 4c, 4e, 4f, 4g, 4i, 4o and 4p exhibited selective and potent inhibitory activity against Staphylococcus aureus with MIC values in the range of 0.125?8 mug/mL. Further, the compounds 4c, 4e and 4g were found to be non toxic to Vero cells (CC50 = >10?>100 mug/mL) and exhibited favourable selectivity index (SI = 40?>200). The compounds 4c, 4e and 4g also showed potent inhibitory activity against various MDR-S. aureus including VRSA. The promising results obtained indicated the potential use of the above series of compounds as promising antibacterial agents for the treatment of multidrug resistant Staphylococcus aureus infections.
