The 1,5-diaryl-3,3-disubstituted-1,5-pentanedione on reaction with ammonium acetate, phosphorus pentoxide and phosphorus pentasulfide gave respective 1,4-dihydropyridine, 4H-pyran and 4H-thiopyran. Novel spiro heterocycles have been obtained by the cyclocondensation of 4H-thiopyran with hydrazine, hydroxylamine, urea and thiourea.
