| Abstract: | A series of derivatives of the natural sesquiterpene lactones alantolactone (1) and isoalantolactone (2) was prepared. The α-methylene-γ-lactone moiety was retained in the structures of these for further modifications using reactions
that affected exclusively the nonconjugated double bonds of the decalin ring.
