A series of 4-isothiazolecarbonitriles was synthesized and screened for in vitro antiviral activity. The effect of various substituents on the phenyl ring, as well as the substitution of the phenyl for other aromatic and heteroaromatic rings, was examined to establish the requirements for optimum activity. The most active member of the series, 3-methylthio-5-phenyl-4-isothiazolecarbonitrile, exhibited a high level of activity against enteroviruses polio 1 and ECHO 9. Preliminary studies on its mechanism of action indicated that this compound had an effect on an early event in the replication of poliovirus type 1. (C) 1998 Published by Elsevier Science Ltd.

The resulting layer structure consists of infinite Ag(I)-S helices linked by the isoxazole moieties, with the latter being stacked above each other. A related complex 2 . AuCl (space group C2/c) features linear S-Au-Cl units associated by weak d(10)-d(10) interactions, while the isoxazole nucleus remains uncoordinated. The solid state structures are compared to those of related isothiazole complexes. (C) 1999 Elsevier Science Ltd. All rights reserved.

In a patnet, author is Ciez, Dariusz, once mentioned the new application about 4397-53-9.

An oxidative dimerization of titanium(IV) enolates derived from menthyl esters of 2-isothiocarboxylic acids leads to radical coupling followed by cyclization. This cascade reaction gives thiazolo[5,4-d]thiazole derivatives as pure enantiomers. Under similar conditions, 2-methylbutyl esters of 2-isothiocyanatocarboxylic acids undergo intermolecular oxidative dimerization to give mixtures of thiazolo[5,4-d]thiazoles and 2,3-diisothiocyanatosuccinates. Application of the soft enolization technique to dimethyl alpha,alpha’-diisothiocyanatodicarboxylic esters gives novel cyclic 1,2-diisothiocyanato-1,2-dicarboxylates. Sodium enolates of 2-isothiocyanatocarboxylates, on the other hand, form 5-imino-2-thioxo-1,3-thiazolidine-4-carboxylic esters by nonoxidative dimerization. The mechanisms of the two reaction pathways are discussed.

A protocol was described to access diverse isothiazoles with functionalization potential via transition metal-free three-component annulation of alkynones, potassium ethylxanthate (EtOCS2K) and ammonium iodide (NH4I). A sequential regioselective hydroamination/thiocarbonylation/intramolecular cyclization cascade achieved the efficient formation of consecutive C-N, C-S and N-S bonds in a one-pot process.

In a patnet, author is Cividino, Pascale, once mentioned the new application about 1504-58-1.

In this study, a novel strategy to access endocyclic sulfoximines in an enantiopure form is reported. The approach is based on a silver nitratecatalyzed cyclo-isomerization reaction of oxygenated propargylic sulfinamides and provides efficiently 5-membered endocyclic sulfoximines (isothiazole 1-oxide). These new heterocyclic scaffolds can be isolated or directly converted into cyclic sulfinamides via Lewis acid-mediated sulfur dealkylation reactions.
