Reactions of selected 3-bromoisothiazole-5-carbonitriles with the secondary dialkylamines pyrrolidine and morpholine

Readily available 3-bromoisothiazole-5-carbonitriles bearing various C-4 substituents [H, CO2R C N and halogen (CI or Br)], react with either pyrrolidine or morpholine to give, in most cases, the 3-amino-substituted derivatives in high yields. The reaction of 3-bromoisothiazole-4,5-dicarbonitrile, however, varied with the nucleophilicity of the dialkylamine: pyrrolidine led to cleavage of the isothiazole ring to give 2-[di(pyrrolidin-1-yl)methylene]malononitrile while morpholine led to the expected 3-(morpholin-4-yl)isothiazole-4,5-dicarbonitrile. By comparison, 3-chloroisothiazole-4,5-dicarbonitrile reacted with pyrrolidine to give surprisingly, 3-chloro-5-(pyrrolidin-1-yl)isothiazole-4-carbonitrile as the major product, while with morpholine the major product was the expected 3-(morpholin-4-yl)isothiazole-4,5-dicarbonitrile. The mechanisms of the transformations are discussed, together with rationalization for the formation of side products. Furthermore, the hydrolytic decarboxylation of methyl and ethyl esters of 3-dialkylaminoisothiazoles using both conventional heating and microwave irradiation is reported. (C) 2014 Elsevier Ltd.

New isothiazole derivatives: Synthesis, reactivity, physicochemical properties and pharmacological activity

The synthesis and biological investigation of the series of amide and ester derivatives 10-20 of 5-(4-chlorobenzoyl)amino-3-methyl-4-isothiazolecarboxylic acid 5 are presented. Because the amide series of 5-benzoylamino-3-methyl-4-isothiazolecarboxylic acid 2 has been studied extensively and from this series denotivir (vratizolin) 4 [1,2] became the antiviral drug. The influence of exchanging the N-benzoyl for a N-(4-chlorobenzoyl) group at position 5 of the isothiazole ring on the pharmacological activity of 5-benzoylamino-3-methyl-4-isothiazolecarboxylic acid 2 derivatives is dealt with here. The effect of structure modifications in the carboxylic group of the 5-(4chlorobenzoyl)amino-3-methyl-4-isothiazolecarboxylic acid 5 series of derivatives on their biological activity is discussed. Some of the tested 5-(4-chlorobenzoyl)amino-3-methyl-4-isothiazolecarboxylamides revealed significant anti-inflammatory activity in carrageenan induced edema and air-pouch inflammation tests. Physicochemical properties of 6-(4-chlorophenyl)-3-methylisothiazolo[5,4-d]-4H-1,3-oxazin-4-one 6 are described. Its use in the synthesis of isothiazole derivatives and its reactivity are also presented.

Synthetic Route of 76-84-6, Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 76-84-6.

New routes to benzothiophenes, isothiazoles and 1,2,3-dithiazoles

4,5-Dichloro-1,2,3-dithiazolium chloride 1 condenses with active methylene compounds, such as malononitrile, barbituric acid and Meldrum’s acid, to give the dithiazol-5-ylidene derivatives, such as 3, 4 and 5, in modest yields. Better yields are obtained from 4-chloro-1,2,3-dithiazole-5-thione 6. Thus the thione 6 condenses with diphenyldiazomethane in a very mild version of the Barton double extrusion synthesis of hindered alkenes; this requires neither heat to extrude nitrogen nor a phosphine to abstract sulfur, to give the alkene 7 (83%) (Scheme 1). This alkene rearranges at room temperature, with loss of hydrogen chloride and sulfur, to give the benzothiophene 13 (89%) in a new thiophene ring-forming reaction (Scheme 2). The thione 6 also condenses with tetracyanoethylene oxide to give a better yield of the dicyanomethylene compound 3 (70%) (Scheme 4). Compound 3, in turn, reacts with morpholine and with chloride ions (Scheme 5) to give 3-morpholino-19 (60%) and 3-chloro- 20 (100%) isothiazole-4,5-dicarbonitrile, in a new isothiazole ring synthesis. Mechanisms are proposed for all of these reactions.

New amides of 5-acylamino-3-methyl-4-isothiazolecarboxylic acid and their immunotropic activity

Several new amides 4 of 5-substituted 3-methyl-4-isothiizolecarboxylic acid were obtained, These compounds have acetylamino or benzoylamino groups in position 5 of the isothiazole ring. In position 4. the carboxylic group was transformed in the amides using amino-acid esters. Activities of the obtained derivatives were checked in the humoral immune response and delayed type hypersensitivity reaction to sheep red blood cells (SRBCs) in vivo.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 76-84-6, you can contact me at any time and look forward to more communication. Application In Synthesis of Triphenylmethanol.
