The optimal method for isolating the sesquiterpene lactone britanin from the aerial part of Inula britannica L. (Asteraceae) was developed. Britanin was functionalized by reacting it with methyl mercaptoacetate.

The reactions with amines of the sesquiterpene lactones britanin and inuchinenolide C isolated from Inula britannica were studied. Migration of the acetyl group during the addition reaction was observed and depended on the nature of the amine and solvent. Compounds with antitumor activity were found among the new amine derivatives.
