Sesquiterpene Lactones as Allelochemicals
Journal of Natural Products, 2006Six new sesquiterpene lactones, annuolide H (3), helivypolides F, H-J (4, 11-13), and helieudesmanolide A (6), together with known compounds, were isolated from polar bioactive fractions of Helianthus annuus cv. SH-222 and Stella fresh leaf water extracts.

Sesquiterpene lactones are a large, diverse group of chemicals found in several plant families that cause allergic contact dermatitis. The biological, botanical, allergenic, and structural significance of sesquiterpene lactones is explored as well as the clinical characteristics of cutaneous reactions.

ChemInform Abstract: Sesquiterpene Lactones of the Umbelliferae
ChemInform, 1986Abstract A survey of sesquiterpene lactones from the species of Umbelliferae is presented. The structures based on predominantly undescribed stereostructural types were derived for the majority of these lactones.

Abstract A novel synthesis of (± )-Vernolepin ( 1 ) is described. A suitably substituted cis -fused 2-oxa-3-decalone precursor ( 29 ) has been constructed starting from 2,5-cyclohexadiene carboxylic acid via an intramolecular cyclopropanation reaction ( 23 to 18 ).

Metabolism of antimalarial sesquiterpene lactones
Pharmacology & Therapeutics, 1990Metabolism of artemisinin derivatives, which are antimalarial sesquiterpenes, appeared to lead to the production of the more polar metabolites in general. Presence of the endoperoxide moiety in the A/B ring structure seems crucial for the expression of antimalarial activity of these compounds.

Abstract Two routes towards (±) quadrone ( 1 ), via an intramolecular Diels-Alder reaction have been studied. The cycloaddition of 5 failed, probably because of prohibitive strain. In the alternative approach, the key step afforded a mixture of the endo- and exo-adducts 6 and 7 .
