Synthesis of 6-Substituted/Unsubstituted- 7,9-diaryl-1,2,4,8-tetraazaspiro[4.5]- decan-3-thiones
摘要:
Some 2,6-diarylpiperidin-4-one thiosemicarbazones (1a-8a), obtained from the corresponding 2,6-diarylpiperidin-4-ones (1-8) on oxidative cyclization with H2O2 at OdegreesC provide 7,9-diaryl-1,2,4,8-tetraaza spiro[4.5]decan-3-thiones(1b-8b) in excellent yields. The structures of these compounds have been established on the basis of their elemental, analytical and spectral data.
