A novel synthetic approach to benzo[d]isothiazole 1,1-diones having a secondary alkyl substituent at the 3-position

A novel method for the synthesis of benzo[d]isothiazole 1,1-diones with a secondary alkyl substituent at the 3-position is described. Treatment of N-tert-butylbenzenesulfonamide (1) with an excess of BuLi, followed by the reaction with methyl 2-arylpropanoate, gave the corresponding ortho-functionalized benzenesulfonamides 2a-d, which underwent cyclization under TMSCl-NaI-MeCN reflux conditions to afford 3-substituted benzo[d]isothiazole 1,1-diones 3a-d.

3,5-[5-Arylisoxazol-3-yl(4,5-dichloroisothiazol-3-yl)]-substituted 1,2,4-and 1,3,4-oxadiazoles: synthesis, palladium complexes, and catalysis of Suzuki reactions in aqueous media

A reaction sequence involving transformations of 5-(4-methylphenyl)isoxazole and 4,5-dichloroisothiazole derivatives containing an amidoxime group at position 3 allowed to synthesize the respective 3,5-isoxazolyl(isothiazolyl)-substituted 1,2,4-oxadiazoles. Selective recyclization of 4,5-dichloro-3-(1De-tetrazol-5-yl)isothiazole and 5-(4-methylphenyl)-3-(1De-tetrazol-5-yl)isoxazole gave 2,5-isoxazolyl-(isothiazolyl)-substituted 1,3,4-oxadiazoles. The obtained compounds combining three azole heterocycles in one molecule formed palladium complexes that showed high catalytic activity in Suzuki reactions in aqueous and aqueous alcohol media. The bimetallic reusable Pd/Fe catalyst obtained from palladium polyazole complex retained high catalytic activity after five uses.

Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 870-50-8, Name is Di-tert-butyl diazene-1,2-dicarboxylate, molecular formula is C10H18N2O4, belongs to isothiazole compound. In a document, author is BUFFEL, DK, introduce the new discover, Recommanded Product: Di-tert-butyl diazene-1,2-dicarboxylate.

The cycloaddition of tri-O-benzyl-2,5-anhydro-D-allononitrile-N-sulfide with dimethyl acetylenedicarboxylate or with dimethyl fumarate followed by DDQ oxidation was found to give the benzoyl protected dimethyl 3-beta-D-ribofuranosyl-isothiazoledicarboxylate 10. This compound was converted to C-nucleosides 7a, 8 and 9, analogues of pyrazofurin, oxoformycin B and formycin respectively. Despite their structural similarities they did show neither antiviral nor antitumor activity.

A theoretical study of the aromaticity of hypervalent sulfur heterocycles

In this paper we report on the heteroaromaticity of 1,2,5-thiadiazole-1,l-dioxide (I) and its isomers 1,2,4-thiadiazole-1,1-dioxide (II), 1,3,4-thiadiazole-1,I-dioxide (III) and 1,2,3-thiadiazoIe-1,1-dioxide (IV) by calculating their electronic structures and estimating their aromatic character in terms of our previously developed criteria: N, MDQ, Delta E-pi L(NLMO) and Delta E-pi L(Boys) as well as comparing their total energies. (I) is shown to be the most aromatic isomer in good agreement with chemical reasoning and experimental evidence. The 1,l-dioxides of thiazole and isothiazole were predicted to be intermediate in aromaticity between thiophene-l, 1-dioxide and the isomers, (I)-(N). N value measures indicate that thiophene-l,1-dioxide would retain a small measure of aromatic character relative to thiophene (N(thiophene) = 0.868, N(thiophene-l,l-dioxide) = 0.389).

Experimental and theoretical investigation of new furan and thiophene derivatives containing oxazole, isoxazole, or isothiazole subunits

Herein, we present joint experimental and theoretical studies on newly designed thiophene- or furan-based oxazole, isoxazole, and isothiazole derivatives. Our synthetic approach towards the preparation of target compounds is based on Van Leusen reaction. By following this reaction, oxazoles (1 and 2) containing the pertinent heterocyclic systems were obtained from the reaction of suitable furan or thiophene derivatives with tosylmethyl isocyanide (TOSMIC). Hereby, three ring systems of furan or thiophene, linked to the oxazole rings at their 2- and 5-positions (3 and 4), were also successfully synthesized for the first time. Reaction of the starting materials containing acetyl groups in their 2-position with dimethyl acetal and following the treatment by hydroxylamine hydrochloride, desired isoxazole derivatives (5 and 6), were obtained. Additionally, isothiazole derivatives (7 and 8) were prepared by following the similar approach to the isoxazole synthesis. Whole of these cyclization reactions occurred with good to excellent yields. Structural analyses of the synthesized compounds were performed by appropriate spectroscopic methods (UV-vis, FT-IR, LC-MS, H-1-NMR, C-13-NMR, and elemental analysis). We also carried out theoretical studies for identifying the structure-activity relationship and determining chemical properties of the studied molecules. For this purpose, we obtained information about structural properties (bond lengths, bond angles, dihedral angles, and dipole moments), band gap energies, and spectroscopic characteristics (UV-vis, FT-IR, H-1-NMR, and C-13-NMR) of the target compounds.
