Abstract

Some new 1,3-disubstituted-4,9-dithia-1,2,6-triazaspiro[4,4]nonan-2-ene-7-one (6, 9 and 11) were synthesized from the cycloaddition reaction of nitrilimines 2 to 3-phenyl-5- phenylmethylene-2-thiooxothiazolidine-4-one (1), 5-phenylmethylene-2-thiooxothiazolidine-4- one (7) and 3-phenyl-2-thiooxothiazolidine-4-one (8), respectively. The new compounds were characterized using IR, 1H NMR, 13C NMR and mass spectra.
