Isolation, Chemical Transformation, and Antifungal Potential of Sesquiterpene Lactones from Inula Racemosa

The present study reports the isolation of two eudesmanolide type sesquiterpenoid lactones, viz. alantolactone and isoalantolactone, from the roots of Inula racemosa Hook L. and their chemical transformations using various reagents. All the compounds isol

Synthesis of Deuterium-Labeled Sesquiterpene Lactones Isolated from Inula helenium L.

Reduction of the vinyl sulfoxides 9 and 10 derived from isoalantolactone (1) and alantolactone (2) with NaBD4 yielded deuterium-labeled lactones 11 and 12.Amalgam reduction of sulfides 7 and 8 or sulfoxides 9 and 10 gave labeled products but not the expected deuterated lactones 11 and 12.Satisfactory deuteration of alantolactone 2 could be achieved by CF3COOD hydrolysis of (tributylstannyl)alantolactone (23) obtained in four steps from alantolactone 2.
