The invention relates to a method for producing at least one compound with Z-1 cycles and between 7 and 16 C atoms with at least one aldehyde group, said method comprising at least the following steps: (a1) oxidation of a composition (A), at least containing one cyclic olefin with Z cycles and between 7 and 16 C atoms and at least two C-C double bonds, using dinitrogen monoxide, to obtain a composition (A1), (a2) isolation of the at least one cyclic olefin comprising Z cycles and between 7 and 16 C atoms with at least two C-C double bonds from the composition (A1) from stage (a1), to obtain a composition (A2), and (b1) isolation of the cyclic compound or compounds with Z cycles and between 7 and 16 C atoms with a keto group from composition (A2) in step ...
