Db. Reddy et al., CYCLOHEXANONE DICARBOXYLATES AS PRECURSORS FOR SELENADIAZOLES AND THIADIAZOLES - PART IV, Indian journal of chemistry. Sect. B: organic chemistry, including medical chemistry, 36(10), 1997, pp. 923-926
The Michael adducts, 4-ketocyclohexane dicarboxylates 2 are converted
to their semicarbazones 3. The latter on reaction with SeO2 and SOCl2
yield a new class of selenadiazoles 4 and thiadiazoles 5, respectively
. They are characterized by their spectral (IR,H-1 NMR and mass) data.
