An Electrochemical Variant in the Syntheses of Exaltone and Muscone: Anodic Fragmentation of α,β-Unsaturated Tosylhydrazones

Article abstract of DOI:10.1002/hlca.19890720627

Ring enlargement of bicyclo<10.3.0>pentadec-1(12)-en-13-one p-toluenesulfonylhydrazone into cyclopentadec-4-yn-1-one was accomplished under mild and controlled anodic oxidation conditions.The mechanism of this fragmentation is reconsidered.
