ELECTROCHEMICAL DEHYDROGENATION OF STEROIDAL .DELTA. SU3,5 XX ENOL ETHERS UNDER BASIC CONDITIONS TO PROVIDE STEROIDAL .DELTA. SU4,6 XX DIENONES

摘要

ABSTRACTAn improved process for the preparation ofsteroidal .DELTA. 4,6 dienones by the electrochemical dehydrogena-tion of the corresponding .DELTA. 3,5 enol ethers under basic con-ditions, using a hlgh potential quinone catalyst, such as2,3-dichloro-5,6-dicyano-benzoquinone, in a partiallyaqueous electrolyte solution.
