摘要：Novel cyclohexanone derivatives of general formula: (wherein R is ahydrocarbon group of 1 to 15 carbon atoms) and new cyclohexanone derivatives ofgeneral formula: (wherein R' and R each is a hydrocarbon group of 1 to 15 carbon atoms)are produced by an electrooxidative coupling of 1,3-cyclohexanedione with a vinyl etherof generat formula: (wherein R is as defined above) in the presence or absense of analcohol of general formula: (wherein R is as defined above). These new cyclohexanonederivatives can be easily converted to N-substituted or unsubstituted-4-oxo-4,5,6,7-tetrahydroindoles, which are of value as intermediates for the production of N-substituted or unsubstituted-4-hydroxyindoles and, thence, to pindolol and its analogs.
