N-Sulfonylamidines. Part IV. Intramolecular cyclization of N-sulfonylamidines of 2-oxoacids: A new synthesis of 3-aminoisothiazole S,S-dioxides

, 1992
N-alkylsulfonylamidines of α-ketoacids 3 bearing both a carbonyl group and at least one H-atom near to the SO2 group give easily an intramolecular ring-closure reaction by action of potassium t-butoxide producing the 3-amino-4,5-dihydro-4-hydroxy ...

Steric effects in quaternizations. Alkylation of pyridine, thiazole, isothiazole and some benzologues with methyl, ethyl and isopropyl iodides

, 1976
Results of quaternization reactions in sulpholane at 65 are reported. A large steric hindrance is noted for quinoline relative to pyridine. A much smaller variation in rate with change in alkyl halide is seen in the benzothiazole/thiazole pair.

Tandem photoarylation-photoisomerization of halothiazoles: synthesis, photophysical and singlet oxygen activation properties of ethyl 2-arylthizole-5-carboxylates.

, 2010
The photochemical reaction between ethyl 2-chlorothiazole5-carboxylate and benzene gave no product. In contrast, the reaction with ethyl 2-iodothiazole-5-carboxylate gave ethyl 3-phenylisothiazole-4-carboxylate.

Synthesis and antiproliferative activity of benzo[d]isothiazole hydrazones

, 2006
Several benzo[d]isothiazole hydrazones have been evaluated for their potential antiretroviral activity. Since a number of these compounds were found to be inactive against viruses, but showed cytotoxicity at micromolar concentrations against the human ...
