Abstract
Dithioesters 2a, b were prepared and methylated to give dimethyl thioesters 3a, b. Azines 4a-d and 5a, b were obtained in one step from 2 with primary diamines or in two steps through 3. Dithioesters 2a, b reacted with amines in ethanol to produce thiosemicarbazones 6a, b and 8a-d, while in butanol reacted with morpholine to form 7a, b
