title: Formation of thiazoles, thiazines, and thiadiazines from 1-phthalazine thiosemicarbazides as potential anticonvulsants.
abstract: 3-Substituted-4-oxothiazolin-2-yl-(1-phthalazinyl)hydrazones, 3-substituted-4-oxo-5,6-dihydro-1,3-thiazin-2-yl-(1-phthalazinyl)hydrazones, and 2-substituted-amino-5-oxo-4-(1-phthalazinyl)-6-hydro-1,3,4-thiadiazines were prepared and tested for their anticonvulsant activity. Some compounds showed weak to moderate anticonvulsant activity.
