Abstract
The syntheses of 5,7-diaryl-2-hydrazino-8-oxo-6-thioxopyrimido[4,5-e] [1,3, 4] thiadiazines 3,2-arylimino-4H/aryI-8-alkyl/arylimino-1,7-dithia-3,4,9-tr iaza-spiro[6.5]decan-5,7-dione 9/12, 2-hydrazino-1,7-dithia-3,4,9-triaza-8- alkyl/aryl-imino-5,10-dioxo-(4H,9H) spiro [6.5]dec-2-enes 14 and their prec ursors have been described.
