Preparation of 1,4-hydrobenzoquinones by the PCC/SiO2-promoted double oxidation of 3-cyclohexene-1,2-diols.
The PCC/SiO2-promoted double oxidation of 3-cyclohexene-1,2-diols, which were easily prepared by the two-step sequence of alpha'-hydroxylation of various conjugated cyclohexenones and the subsequent nucleophilic carbonyl addition of alkyl anions, produced diversely substituted 1,4-hydrobenzoquinones.
