The title compounds were prepared starting from the dihydropyrrolones 4–6. Nucleophilic displacement and ring closure yielded the 1H-pyrrolo[3,2-c]isothiazol-5(4H)-ones 8 and 10. The fused systems formed salts with strong acids and electrophiles (1

The title compounds were prepared starting from pyrrolinone 4. Nucleophilic-displacement and ring-closure reactions yielded the dithiolopyrrole 5a, which formed salts with electrophiles (7, 8) as well as with bases. The crystal structure of 5a was de

Die Titelverbindungen 7-9 reagieren mit Nucleophilen an der Lactimethergruppe, wahrend bei 6 Umsetzungen in 4-Stellung, bei der bromierten Verbindung 14 in 4- wie auch in 6-Stellung moglich sind. The title compounds 7-9 react with nucleophiles as lac
