β¦ Synopsis
2-(2-Dithianyl1benzhydrol.s (_Z a-c) undergo facile cycloaddition reaction with maleic anhydride under thermal conditions to give l-phenylnaphthalenes (1 a-c) in one step. The naphthalenes (1 a-c) have been converted

Both enantiomers of 1,7-dioxaspiro[5.5]undecane, the major pheromone components of the olive fruit fly (Bactrocea oleae), have been synthesized by using a new method based on the intramolecular asymmetric oxyselenenylation of 4-(3,4-dihydro-2H-pyran-6-yl)butan-1-ol.
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
