2 4 ‐methyl‐dihydro‐γ‐ionone and trans‐dihydro‐γ‐irone have been prepared and cyclized to 1,1‐dimethyl‐6‐ethyl‐6‐hydroxy‐octalene (XVII) and 1,1,2,6‐tetramethyl‐6‐hydroxy‐octalene (XVIII) respectively. Whereas the first isomerization is much easier than that of dihydro‐γ‐ionone, the second is much more difficult.
