- Synthesis and reaction of N-sulfenylpyrroles
-
N-Sulfenylpyrroles were synthesized by the condensation of N-unsubstituted sulfenamides with 1,4-dicarbonyl compounds, such as hexane-2,5-dione or 2,5-dimethoxytetrahydrofuran. Primary amines as nucleophiles did not attack to the sulfur atom of the N-S bo

- A facile synthesis of 1,2-benzisothiazolin-3-ones from thiosalicylates
-
Synthesis of 1,2-benzisothiazolin-3-ones by cyclization of 2- sulfenamoylbenzoates, which were prepared from amination of thiosalicylates by hydroxylamine-O-sulfonic acid, was examined. Although treatment of methyl 2-sulfenamoylbenzoate on heating gave unexpected 2-(2- methoxycarbonylphenylthio)-1,2-benzisothiazolin-3-one, the treatment with base at room temperature afforded 1,2-benzisothiazolin-3-one in a good yield.
