The cyclization of 2-substituted N-arylamides of 3-alkylaminobut-2-enethioic acid gave a series of new 2-alkyl-5-arylimino-2,5-dihydroisothiazole derivatives containing a benzoyl or ester group at position 4. A study was carried out on the course of this reaction in the presence of various oxidizing agents, including halogens, N-bromosuccinimide, hydrogen peroxide. Some of the isothiazoles obtained in this work exhibited cytotoxic activity against both normal and cancer cell lines.

Notes
The signal of the (E)-isomer was not seen due to low intensity and broadening.
