Functionalized isoxazole and isothiazole ligands: design, synthesis, palladium complexes, homogeneous and heterogeneous catalysis in aqueous media

Homogenous and heterogeneous palladium catalysts with functionalized izoxazole and isothiazole ligands were developed for the cross-coupling reactions. The catalysts possessed high activity and were suitable for the repeated use. Compared with commonly used organic solutions, application of water and its mixtures with methanol as a reaction medium significantly intensifies catalysis with no side being formed. The obtained results are promising for the development of effective and ecologically friendly technologies of synthesis of important compounds such as polyfunctional biaryls, arylated olefins, acetylenes and their heterocyclic analogs.

Functional Derivatives of 4-Formyl-2-methoxyphenyl Pyridine-4-carboxylate

Acylation of vanillin with isonicotinoyl chloride gave 4-formyl-2-methoxyphenyl pyridine-4-carboxylate which was converted into a number of functional derivatives, including those containing isoxazole and isothiazole heterocycles. In particular, the condensation of the title compound with primary amines afforded the corresponding Schiff bases. 4-Formyl-2-methoxyphenyl pyridine-4-carboxylate and one of the Schiff bases derived therefrom were reduced with sodium triacetoxohydridoborate to the corresponding alcohol and amine which were acylated with 5-arylisoxazole- and 4,5-dichloroisothiazole-3-carbonyl chlorides to obtain esters and amides having isoxazole and isothiazole fragments. The synthesized compounds readily formed complexes with palladium(II) chloride, which showed a high catalytic activity in the Suzuki reaction of 3-bromobenzoic acid with 4-methoxyphenylboronic acid in water in the absence of an organic solvent.

Antidermatophytic activity of pyrazolo[3,4-c]isothiazoles: a preliminary approach on 4-chlorophenyl derivative for evaluation of mutagenic and clastogenic effects on bacteria and human chromosomes in vitro

The antifungal activity of eight pyrazolo[3,4-c]isothiazole derivatives was evaluated on five dermatophytes: three were of an anthropophilic species (i.e., Epidermophyton floccosum, Trichophyton rubrum, and Trichophyton tonsurans) and two were of a geophilic species (i.e., Microsporum gypseum and Nannizzia cajetani). The new compounds proved to be unlikely effective in inhibiting the growth of the different strains. In general, the fungi parasitic on man were more sensitive than the geophilic species. This fact can be positive for a possible practical-therapeutic utilization of this class of compounds. To verify their possible use against fungi of medical interest, the most interesting substance at low doses, 6-(4-chlorophenyl)-4-methyl-6H-pyrazolo[3,4-c]isothiazol-3-amine, was chosen to perform in vitro genotoxicity tests using the following: Salmonella/microsome test (SAL), sister chromatid excange test (SCE), cytokinesis-blocked micronucleus test (CBMN), and its improvement (Ara-C/CBMN). The compound showed no mutagenic activity at low doses, whereas at the highest dose (100 mu g/mL), it caused a generalized cytotoxic effect. The high growth inhibition exerted on fungi at the lowest dose and the concomitant lack of genotoxicity, at least until the dose of 50 mu g/mL, might suggest the compound as a safe candidate as an antidermatophytic substance.

Recent Advances in the Synthesis and Reactivity of Isothiazoles

Isothiazoles represent an important class of five-membered sulfur heterocycles that are widely utilized in medicinal chemistry and organic synthesis due to the unique properties of two electronegative heteroatoms in a 1,2-relationship. However, in contrast to other 1,2-azoles, the facile assembly of isothiazoles has always been considered a substantial challenge. In the last decade, major advances have taken place in the fields of synthesis and functionalization of isothiazoles that make them accessible to a wide range of interested chemists through unprecedented pathways. New condensation methods have emerged that address the challenges posed by unstable thiohydroxylamine. New metal-catalyzed approaches have been reported that deliver densely decorated isothiazoles bearing various sensitive functional groups. New functionalization strategies have been developed through both cross-coupling and direct C-H activation chemistry. Finally, the emergence of novel heterocyclic architectures based on isothiazole opens the door for future investigations of this versatile heterocyclic scaffold. This review covers the period from January 2004 to December 2018 and is intended as a sequel to the review on isoxazoles, which represent another class of synthetically-important 1,2-azoles (see Adv. Synth. Catal. 2015, 357, 2583-2614).

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 61990-51-0, you can contact me at any time and look forward to more communication. HPLC of Formula: C14H22N2O4.

Rational design of diketopyrrolopyrrole-based multifunctional materials for organic light-emitting diodes and organic solar cells

A series of donor-acceptor diketopyrrolopyrrole derivatives has been investigated to reveal their optical, electronic, and charge transport properties for applications in organic light-emitting diodes (OLEDs) and organic solar cells (OSCs). The calculated results show that their optical, electronic, and charge transport properties are affected by the different end groups. The introduction of the 2,5-diphenylthiophene, benzo[c]isothiazole, benzo[c]thiophene, benzo[c]thiophene, 2,4-dihydrobenzo[d]thiazole, and thieno[3,4-b][1,4] dioxine end groups can broaden absorption spectrum and improve charge transport property of the designed compounds. Our results suggest that the designed compounds can serve as donor materials for OSCs and luminescent materials for OLEDs. In addition, the mobility of the designed compounds is also investigated. They are expected to be promising candidates for hole and electron transport materials. On the basis of investigated results, we proposed a rational way for the design of multifunctional materials for OLED and OSC applications.

Morphological study of Trichophyton rubrum: ultrastructural findings after treatment with 4-amino-3-methyl-1-phenylpyrazolo-(3,4-c)isothiazole

The antifungal activity of 4-amino-3-methyl-1 -phenylpyrazolo-(3,4-c)isothiazole was studied on Trichophyton rubrum. The compound, at concentrations between 20 and 100 mu g ml(-1), induces a remarkable reduction in the growth and causes deep morphogenetic anomalies. The ultrastructural modifications have demonstrated that the compound targets the cell membrane of the fungus, breaking down not only the endomembrane system, but also the ‘outer’ membrane, with consequent extrusion of materials in the medium. The results suggests a mechanism of action similar to other azoles clinically utilized.
