A series of new tricyclic fluoroquinolones was prepared by replacing fluorine atoms in derivatives of 2-R-8-Y-7-oxo-9,10-difluoro-7H-1,3,4-thiadiazino[6,5,4-i]quinoline-6-carboxylic acids. In acids and esters containing a hydrogen atom in position 8 occurred replacement of F-10 by amine rests, and in compounds with a fluorine in position 8 was substituted either F-8 or F-10 and F-8 depending on the amine character.

Depending on the conditions, 3-(4-R-thiosernicarbazido)-2-polyfluorobenzoylacrylates can be converted into the corresponding potassium salts, [1,3,4]thiadiazino[6,5,4-ij]quinolines, and pyrazole or 1,3,4-thiadiazole derivatives.
