Chemical modification of Britanin and of inuchenolide C

Article abstract of DOI:10.1007/BF01375118

Analogs of helenalin possessing a broad spectrum of biological activity have been synthesized from the readily available sesquiterpene lactones britanin and inuchenolide C. Conditions for the hydrolysis, oxidative transformations, and skeletal rearrangements of the pseudoguaianolides that are characteristic for plants of the genus Inula have been studied.
