AbstractThe 1H and 13C NMR spectra of the trans,trans‐, cis,cis‐ and cis‐C‐3–C‐4, trans‐C‐7–C‐8‐germacrones and of the cis‐C‐2–C‐3, trans‐C‐7–C–8, trans‐C‐2–C‐3, cis‐C‐7–C‐8‐ and cis,cis‐isogermacrones are analysed. The last two isogermacrones are new compounds. The C‐2–C‐3 double bond in the previously described isogermacrone is found to be of cis configuration, contrary to the hitherto accepted trans arrangement.
