Isothiazoles. Part XII. Isothiazole analogues of phenothiazines

Journal of the Chemical Society C: Organic, 1968
The syntheses of isothiazole analogues [(V) and (VI)] of certain phenothiazines and 4-substituted phenothiazines, where the substituent is dialkylaminoalkyl, 1-piperazinylalkyl, or piperidinoalkyl are described. None of these possesses advantageous pharmacological properties.

Pyrazolo[3,4-c]isothiazole and isothiazolo[4,3-d]isoxazole derivatives as antifungal agents

Pharmaceutical Biology, 2011
Context: The diseases of plants and humans due to pathogenic fungi are increasing. Among the substances used tocombat fungi, the azoles are of primary interest, both in agricultural field both in health. To avoid fungal resistancephenomena, the synthesis

Isothiazoles. Part XIII. Isothiazole sulphides and sulphones

Journal of the Chemical Society C: Organic, 1971
The synthesis of di-isothiazolyl sulphides and their oxidation to sulphoxides and sulphones are described. Isothiazolylphenyl sulphones are prepared by condensation of sodium benzenesulphinates and 5-bromo-3-methyl-4-nitroisothiazole. None of these compounds possess useful biological properties.

Isothiazoles. Part 12: Isothiazolylphosphonates, a new class of isothiazole dioxides

Tetrahedron, 2001
Abstract We describe a mild and efficient method to prepare 3-amino-4,5-dihydro-5-isothiazolylphosphonates from 3-amino-5-unsubstituted isothiazole dioxides. Starting from 3-amino-5-bromo-isothiazole dioxides either 3-amino-5-isothiazolylphosphonates or 5-diethoxyphosphoryl-4,5-dihydro-4-isothiazolylphosphonates were prepared ...

Synthesis of isothiazoles

Tetrahedron, 1969
Abstract A method has been devised whereby a substituted isoxazole (I) can be efficiently converted to an isothiazole (III) with a similar substitution pattern. The isoxazole ring is opened by reduction with Raney nickel, and the resulting enamino ketone (II) is treated with phosphorus pentasulfide and chloranil to give the corresponding isothiazole ...

Über Isothiazole

Angewandte Chemie, 1963
AbstractDas Ringsystem der nicht annellierten 1.2‐Thiazole (=Isothiazole) ist erst in neuester Zeit zugänglich geworden. Vier Synthesen und zahlreiche Umsetzungen eröffnen neue Wege zu Verbindungen, die als Zwischenprodukte und Analoga zu Naturstoffen und bekannten Pharmazeutika Interesse beanspruchen.

Condensed isothiazoles. Part 5. Thieno[2,3-d]isothiazoles and thieno[3,2-d]isothiazoles

Journal of the Chemical Society, Perkin Transactions 1, 1980
2,3-Disubstituted thiophens containing a sulphur function (SH, SMe, or SCN) and a carbonyl group (CHO or Ac) have been prepared and converted into thieno[2,3-d or 3,2-d]isothiazoles. Methods used to prepare 1,2-benzisothiazoles are often inapplicable in the thiophen series. For example, an (E)-methyl (2-methylthio-3-thienyl)O-p-nitrobenzoylketoxime (6)
