Treatment of the dimethyl acetals of citral (1) and farnesal be subjected to a Diels-Alder reaction, which allows further synthetic elaboration. In particular, in the case of farnesal (2) with the superbase "LICKOR" in THF at low temperatures induces regioselective metallation at the allylic methyl
