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.

The palladium-catalyzed reaction of 5-bromo-3-diethylamino-4-(4-methoxyphenyl)-isothiazole 1,1-dioxide(3) with a variety of vinyl-, aryl-, heteroaryl- and alkynylstannanes 4 provides a general and efficient method for the synthesis of 5-substituted isothiazole 1,1-dioxides 5. Different reaction conditions (catalyst, solvent, temperature) were tested for the coupling. The best results were obtained using toluene at reflux and benzylchlorobis(triphenylphosphine)palladium as catalyst. When organostannanes appeared to be less reactive, prolonged heating resulted in the formation of variable amounts of the reduction product 3-diethylamino-4-(4 methoxyphenyl)-isothiazole 1,1-dioxide(1).

pMATM2-b-p(MMA-co-BMA) diblock copolymers composed of a block of poly[bis(trimethylsiloxy)methylsilyl methacrylate] (MATM2) and a second block of a random copolymer of methyl methacrylate (MMA) and n-butyl methacrylate (BMA) were synthesized by the reversible additionfragmentation transfer process with controlled molar masses and low molar mass dispersities. Paints were formulated using these diblock copolymers as binders, without any biocides, or associated with low amounts of biocidal compounds such as dicopper oxide (Cu2O), 4,5-dichloro-2-n-octyl-4-isothiazole-3-one (DCOIT), and 4-bromo-2-(4-chlorophenyl)-5-(trifluoromethyl)-1H-pyrrole-3-carbonitrile. All the coatings exhibited a hydrophobic surface at the initial stage with an evolving surface chemistry when immersed in artificial seawater. The erosion of the coatings was shown to be driven by the molar proportion of MATM2 units in the diblock copolymer. The antifouling properties were evaluated by in situ static immersion in the Mediterranean Sea. Cu2O (20 wt %)-DCOIT (2 wt %)-based coatings with 30 mol % of MATM2 in the seawater-hydrolyzable binder exhibited similar antifouling performances to a commercially available self-polishing coating over 16 months of field immersion. Contact angles and mass loss measurements, as well as scanning electron microscopy observations enabled the investigation of the parameters influencing the antifouling activity of the coatings.

Chemistry, like all the natural sciences, begins with the direct observation of nature¡ª in this case, of matter.3466-32-8, Name is 1-Bromo-4-(methylsulfonyl)benzene, SMILES is O=S(C1=CC=C(Br)C=C1)(C)=O, belongs to isothiazole compound. In a document, author is Ioannidou, Heraklidia A., introduce the new discover, Product Details of 3466-32-8.

The conversion of isothiazoles into pyrazoles on treatment with hydrazine is investigated. The influence of various C-3, C-4 and C-5 isothiazole substituents and some limitations of this ring transformation are examined. When the isothiazole C-3 substituent is a good nucleofuge, 3-aminopyrazoles are obtained. However, when the 3-substituent is not a leaving group it is retained in the pyrazole product. Treatment of 4-bromo-3-chloro-5-phenylisothiazoie 56 or 3-chloro-4,5-diphenylisothiazole 57 with anhydrous hydrazine at ca. 200 degrees C for a few minutes gives the corresponding 3-hydrazinoisothiazoles 61 and 64 respectively in high yields; the stability of these new hydrazines is investigated. 5,5′-Diphenyl-3,3′-biisothiazole-4,4′-dicarbonitrile 78 reacts with hydrazine to give 5,5′-diphenyl-3,3′-bi(1H-pyi-azole)-4,4′-dicarbonitrile 79. Methylhydrazine reacts with 3-chloro-5-phenytisothiazole-4-carbonitrile 1 to give 3-(1-methylhydrazino)-5-phenylisothiazole-4-carbontrile 83 and 3-amino-lmethyl-5-phenylpyrazole-4-carbonitrile 84. All products are fully characterised and rational mechanisms for the isothiazole into pyrazole transformation are proposed. (C) 2009 Elsevier Ltd. All rights reserved.
