Reaction of 1-(1-nitroalkyl)-cycloalkenes epoxide with silica gel afforded the corresponding 2-(1-nitroalkylidene)-cycloalkanols which were further oxidized with chromic acid-sulfuric acid in 2-(1-nitroalkylidene)-cycloalkanones.

oxidation of 1-nitromethylcycloalkenes with m-chloroperbenzoic acid afforded the corresponding 2-nitromethyl-2-cycloalkenols, which were further converted into 2-nitromethyl-2-cycloalkenones.
