Synthesis of Steroidal Spiro-1′,2′,4′-triazolidine-3′-thiones
摘要:
Steroidal ketone thiosemicarbazones (4-6), obtained from the corresponding ketones(1-3), on oxidative cyclization with H2O2 at 0 degrees C provide title compounds (7-9), respectively The structures of these compounds have been established on the basis of their elemental analytical and spectral data.
