Abstract:
Summary Acetic anhydride treatment of farnesic acids leads to the expected cyclohexenones (V and VI) and to the alternative formation of the 3. 2. 0]-bicycloheptenones (IV orVII) depending on the geometry of the central double bond of the acid.This work has received financial support from Consiglio Nazionale delle Ricerche.
