4,5-dialkyl-substituted 3-oxo-(2H)-isothiazole 1,1-dioxides in reactions with diazomethane

It has been established that the interaction of diazomethane with 4,5-dialkyl-substituted 3-oxo-(2H)-isothiazole 1,1-dioxides proceeds in two stages. Initially alkylation of the sulfonimide nitrogen atom and the carbonyl group oxygen atom occurs (in a ratio of similar to 3:2), then there is a regioselective cycloaddition of diazomethane at the C=C double bond with the formation of the corresponding N-methyloxoisothiazolopyrazolines and 3-methoxyisothiazolopyrazolines.

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 35271-74-0. COA of Formula: C11H11ClO4.

COMPARATIVE REACTIVITY OF 3-METHYL-5-PHENYLISOXAZOLE AND 3-METHYL-5-PHENYLISOTHIAZOLE AGAINST ELECTROPHILIC COMPOUNDS

A comparative study of reactions of 3-methyl-5-phenylisoxazole and 3-methyl-5-phenylisothiazole with electrophilic compounds in the presence of n-BuLi, LICA or LICA-TMEDA is reported. By using LICA-TMEDA, regioselective reactions of the heterocyclic compounds at the C-3 methyl group are obtained. With n-BuLi or LICA and the isoxazole derivative a product mixture at the C-4 position and the C-3 methyl group is found. In the case of isothiazole compound, only with methyl iodide and n-BuLi, the dialkylated product at both positions is formed.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 121-89-1, you can contact me at any time and look forward to more communication. Recommanded Product: 3′-Nitroacetophenone.

A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 93-97-0, Name is Benzoic anhydride, molecular formula is C14H10O3.

Reinvestigating the Reaction of 1H-Pyrazol-5-amines with 4,5-Dichloro-1,2,3-dithiazolium Chloride: A Route to Pyrazolo[3,4-c]isothiazoles and Pyrazolo[3,4-d]thiazoles

The reaction of Appel salt 1 with 1H-pyrazol-5-amines 2 gives main products N-(4-chloro-5H-1,2,3-dithiazol-5-ylidene)-1H-pyrazol-5-amines 3, and 6H-pyrazolo[3,4-c]isothiazole-3-carbonitriles 5, together with several minor side products. When the pyrazoles are N-1 methylated, the product ratio 3:5 can be modified by adjusting the pH of the reaction medium: acidic conditions favor formation of the dithiazolylidenes 3, while basic conditions favor formation of pyrazolo[3,4-c]isothiazoles S. Furthermore, thermolysis of N-(4-chloro-5H-1,2,3-dithiazol-5-ylidene)-1H-pyrazol-5-amines 3 gives 1H-pyrazolo[3,4-d]thiazole-5-carbonitriles 4. Single crystal X-ray crystallography supports the structure of 4,6-dimethyl-6H-pyrazolo-[3,4-c]isothiazole-3-carbonitrile (5a) and helps resolve a previous incorrect structural assignment of 1H-pyrazolo[3,4-d]thiazole-5-carbonitriles 4.

Electrospinning of pyrazole-isothiazole derivatives: nanofibers from small molecules

We investigate the electrospinning of small molecules, specifically designed peptide derivatives of the pyrazole-isothiazole scaffold. Such non-natural peptides enhance the spectrum of fundamental materials used for electrospinning. Unlike standard electrospun materials, our peptides are not polymeric, but able to aggregate in solution and especially during processing. They contain donor/acceptor groups that can form hydrogen bonds, and groups that are able to generate pi-stacking interactions, which are known as important requirements for assembly processes. The pyrazole-isothiazole derivatives were synthesized by means of a 1,3-dipolar cycloaddition reaction, which is completely regioselective, affording only one isomer. We demonstrate that our compounds can be electrospun from fluoroalcohol solution into solid, quasi-endless micro- and nanofibers. The electrospinnability varies substantially, depending on the amino acids linked to the scaffold. Some compounds provide only short fibers, while Fmoc-glycyl-(N-benzyl)-pyrazole-isothiazole-tert-butyl carboxylate-1,1-dioxide forms continuous, homogenous, and bead-free fibers (droplet-like beads are a common problem in electrospinning). We analyzed the compounds and the fibers with various spectroscopic techniques (MS, IR and Raman). Electrospinning does not change chemical composition and configuration, suggesting the monomeric form of the compounds even in the fibers. Interestingly, we found that the stereochemistry of the scaffold can affect the ability of the peptide to be electrospun.

Synthesis of N,N ‘-linked bisazaheterocycles with sulfonamide structure via oxidation of S,N-heteroaromatic cations

N-Phthalimidyl- and N-quinazolinyl-substituted 3-hydroperoxy-, 3-hydroxy- and 3-oxoisothiazole 1,1-dioxides have been synthesized by the sequence of oxidation reactions from N,N’-linked isothiazolium perchlorates with hydrogen peroxide, MMPP, and pyridinium dichromate. Isothiazolium salts without acceptor substituents did not give N-substituted sultams. Novel N,N’-bisazaheterocycles were investigated as inhibitors of acetylcholinesterase (AChE) and human leukocyte elastase (HLE). Two 2,3-dihydro-3-hydroperoxy-2-(phthalimid-1-yl)isothiazole 1,1-dioxides were found to inhibit AChE.

Selective Aza Diels-Alder and Domino [4+2]/[2+2] Cycloaddition Reactions of Arynes with N-Sulfonyl Ketimines

Transition-metal-free inverse electron-demand aza Diels-Alder and domino [4+2]/[2+2] cycloaddition reaction of arynes and N-sulfonyl ketimines has been demonstrated. This novel, mild, and efficient protocol allows rapid access to isothiazole dioxide-fused dihydroquinoline or dihydrocyclobutaquinoline derivatives selectively by simply varying the equivalents of aryne precursors. The application of this method has been amply illustrated in the synthesis of 2,4-diarylquinolines.

Isothiazoles as active-site inhibitors of HCVNS5B polymerase

Isothiazole analogs were discovered as a novel class of active-site inhibitors of HCV NS5B polyrnerase. The best compound has an IC50 of 200 nM and EC50 of 100 nM, which is a significant improvement over the starting inhibitor (1). The X-ray complex structure of I with HCV NS5B was obtained at a resolution of 2.2 angstrom, revealing that the inhibitor is covalently linked with Cys 366 of the ‘primer-grip’. Furthermore, it makes considerable contacts with the C-terminus, P-loop, and more importantly, to the active-site of the enzyme. The uniqueness of this binding mode offers a new insight for the rational design of novel inhibitors for HCV NS5B polymerase. (c) 2006 Elsevier Ltd. All rights reserved.
