Synthesen in der Isocamphanreihe, 39. Mitt.: Verbesserung derDiels-Alder-Reaktion von Cyclopentadien mit Mesityloxid durch Ultraschall und eine neue Synthese von Dehydrocamphen
摘要:
The synthesis of the valuable terpenic synthon 2-acetyl-3,3-dimethylbicyclo[2.2.1]hept-5-tene is clearly improved concerning the yield and especially the reaction time by applying ultrasound on the Diels-Alder reaction of cyclopentadiene with mesityl oxide. A new synthesis of dehydrocamphene and its odour impression is described.
