Abstract In leaves of Nicotianaundulatainoculated with TMV, 19 sesquiterpenoids were detected as stresscompounds. Among them, dehydrocarissone, capsidiol 3-acetate, aubergenone, 4- epi -aubergenone, trans -dihydrocarissone, 1,2-dehydro-α-cyperone and 3- epi -3-hydroxysolavetivone are novel tobacco stresscompounds.

Syntheses of 4-epi-aubergenone, a sesquiterpenoidrelated to eudesmane, are described. One synthesis afforded this sesquiterpenoid as a racemate (12) whereas another, utilizing (+)-carissone as starting material, afforded an enantiomer (12a). The fact that naturally occurring aubergenone is the C(4) epimer of the thermodynamically more stable synthetic 12 was revealed by the discovery that it was completely
