Generation of benzosultams via a radical process with the insertion of sulfur dioxide

An efficient route to diverse 3-sulfonated-2,3-dihydrobenzo[d] isothiazole 1,1-dioxides is achieved through a three-component reaction of 2-ethynylbenzenesulfonamides, DABCO-bis(sulfur dioxide), and aryldiazonium tetrafluoroborates. The corresponding sulfonated benzosultams are produced in moderate to good yields. During the reaction process, the in situ generated arylsulfonyl radical via addition of an aryl radical to sulfur dioxide and the subsequent single electron transfer would be the key steps for the final outcome. DABCO acts as the carrier for single electron transfer, as well as a base to promote the C-N bond formation.

Regiospecific Suzuki coupling of 3,5-dichloroisothiazole-4-carbonitrile

3,5-Dichloroisothiazole-4-carbonitrile 1 reacts with aryl- and methylboronic acids to give in high yields the 3-chloro-5-(aryl and methyl)-isothiazole-4-carbonitrile 2 regiospecifically. The reaction was optimized with respect to base, phase transfer agent and palladium catalyst. Suzuki coupling at C-5 was also achieved in high yield using potassium phenyltrifluoroborate. The regiospecificity of either coupling method is maintained with 3,5-dibromoisothiazole-4-carbonitrile 4 to give exclusively 3-bromo-5-phenylisothiazole-4-carbonitrile 5. Suzuki cross-coupling conditions applied to 3-chloro-5-phenylisothiazole-4-carbonitrile 2a gave 3-phenoxy-5-phenylisothiazole-4-carbonitrite 6, which was prepared independently, and not the 3-phenyl derivative. All isothiazole products were fully characterized.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 39515-51-0, in my other articles.

Synthesis and antiproliferative activity of benzo[d]isothiazole hydrazones

Several benzo[d]isothiazole hydrazones have been evaluated for their potential antiretroviral activity. Since a number of these compounds were found to be inactive against viruses, but showed cytotoxicity at micromolar concentrations against the human CD4(+) lymphocytes (MT-4) that were used to support HIV-1 growth, they were further tested for antiproliferative activity. The compounds resulted as being cytotoxic for MT-4 cells and new derivatives which were rationally designed and synthesized, were tested for antiproliferative activity against several leukaemia and solid, tumour cell lines. In addition, these compounds were evaluated against normal cell lines. Compound 2h proved to be the most active compound and the fragment -CO-NH-N=CH-2-hydroxyphenyl was identified as being very important for biological activity, suggesting intramolecular, hydrogen bond formation or favourable mutual disposition between two important centres in the pharmacophore. H-1-NMR spectra have been explained with the support of a conformational analysis. (c) 2006 Elsevier SAS. All rights reserved.

Coordination chemistry of thiazoles, isothiazoles and thiadiazoles

Thiazole derived compounds have great potential in medicinal-and agro-chemistries, catalysis, cosmetic industry, corrosion protection, light harvesting, production of light-emitting diodes (LEDs), photochromes and molecular switches or nonlinear optical materials. In spite of that, not much attention has been paid to the coordination chemistry of this class of versatile and polyfunctional heterocyclic ligands. This review intends to systematize the existing information in this field and to highlight some perspectives in the synthesis and applications of 1,3-thiazole, isothiazole and thiadiazole metal complexes.

Diarylheterocycle Core Ring Features Effect in Selective COX-1 Inhibition

The COX-1 isoenzyme plays a significant role in a variety of diseases, as it catalyzes the bioprocesses behind many health problems. Among the diarylheterocycle class of COX inhibitors, the isoxazole ring has been widely used as a central heterocycle for the preparation of potent and selective COX-1 inhibitors such as P6 [3-(5-chlorofuran-2-yl)-5-methyl-4-phenylisoxazole]. The role of the isoxazole nucleus in COX-1 inhibitor selectivity has been clarified by preparing a set of new diarylheterocycles with various heterocycle cores. Replacement of isoxazole with isothiazole or pyrazole gave a drastic decrease in COX-1 inhibitory activity, whereas the introduction of an electron-donating group (EDG) on the N-aryl pyrazole allowed recovery of COX-1 inhibitory activity and selectivity. The EDG-equipped 5-(furan-2-yl)-1-(4-methoxyphenyl)-3-(trifluoromethyl)-1H-pyrazole (17) selectively inhibits COX-1 activity (IC50=3.4 mu M; 28?% COX-2 inhibition at 50 mu M), in contrast to its inactive analogue, 3-(furan-2-yl)-1-phenyl-5-(trifluoromethyl)-1H-pyrazole, which does not bear the methoxy EDG. Molecular docking studies of compound 17 into the binding site of COX-1 shed light on its binding mode.
