Isoalantolactone

Description

Isoalantolactone belongs to the class of organic compounds known as eudesmanolides, secoeudesmanolides, and derivatives. These are terpenoids with a structure based on the eudesmanolide (a 3,5a,9-trimethyl-naphtho[1,2-b]furan-2-one derivative) or secoeudesmanolide (a 3,6-dimethyl-5-(pentan-2-yl)-1-benzofuran-2-one derivative) skeleton. Based on a literature review a small amount of articles have been published on Isoalantolactone.
