Jensen, Klaus G. published the artcilePhosphoramides. XIX. Phosphorus pentoxide amine hydrochloride reagents in the synthesis of 3-amino-1,2-benzisothiazole 1,1-dioxides and 3-aminothieno[3,4-d]isothiazole 1,1-dioxides, Name: 3-Aminobenzo[d]isothiazole 1,1-dioxide, the publication is Zeitschrift fuer Naturforschung, Teil B: Anorganische Chemie, Organische Chemie (1981), 36B(12), 1640-3, database is CAplus.

Aminobenzisothiazole dioxides I (R = H, R¹ = alkyl, cycloalkyl; RR¹N = morpholino, piperidino) were prepared by heating saccharin and the hydrochlorides of primary and secondary aliphatic amines with P₂O₅ and N,N-dimethylcyclohexylamine at 240°. 3-Aminothienoisothiazole dioxides II (R² = Pr, Me₂CHCH₂, EtCHMe) were similarly prepared from thieno[3,4-d]isothiazol-3(2H)-one 1,1-dioxide. In biol. screening against lymphocytic leukemia I were inactive.

Zeitschrift fuer Naturforschung, Teil B: Anorganische Chemie, Organische Chemie published new progress about 7668-28-2. 7668-28-2 belongs to isothiazole, auxiliary class Sulfamide,Amine,Benzothiazole, name is 3-Aminobenzo[d]isothiazole 1,1-dioxide, and the molecular formula is C7H6N2O2S, Name: 3-Aminobenzo[d]isothiazole 1,1-dioxide.
