G. Buchbauer et al., SYNTHESES IN THE ISOCAMPHANE SERIES .39. IMPROVEMENT OF THE DIELS-ALDER REACTION OF CYCLEPENTADIENE WITH MESITYLOXIDE BY MEANS OF ULTRASOUND AND A NEW SYNTHESIS OF DEHYDROCAMPHENE, Monatshefte fuer Chemie, 125(8-9), 1994, pp. 921-925
The synthesis of the valuable terpenic synthon 2-acetyl-3,3-dimethylbi
cyclo[2.2.1]hept-5-tene is clearly improved concerning the yield and e
specially the reaction time by applying ultrasound on the Diels-Alder
reaction of cyclopentadiene with mesityl oxide. A new synthesis of deh
ydrocamphene and its odour impression is described.
