Abstract: The spiro heterocycles, spiro-4H-pyra pyrazolidinedione/isoxazolidinedione/ pyrimidinetrione/thioxopyrimidinedione and spiro-4H-pyran aminopyrazolidinone/ isoxazolidinone/ hydroxypyrimidinonel mercaptopyrimidinone have been prepared from 3,3-disubstituted 1,5-diaryl-1,5-pentanedione. All the compounds have been characterised by spectral parameters.
