Common Name

(3ar,4r,9r,9bs)-6-formyl-9-hydroxy-9-methyl-3-methylidene-2-oxo-3ah,4h,5h,9ah,9bh-azuleno[4,5-b]furan-4-yl 2,3-dimethyloxirane-2-carboxylate

Description

Eupachinilide G belongs to the class of organic compounds known as gamma butyrolactones. Gamma butyrolactones are compounds containing a gamma butyrolactone moiety, which consists of an aliphatic five-member ring with four carbon atoms, one oxygen atom, and bears a ketone group on the carbon adjacent to the oxygen atom. (3ar,4r,9r,9bs)-6-formyl-9-hydroxy-9-methyl-3-methylidene-2-oxo-3ah,4h,5h,9ah,9bh-azuleno[4,5-b]furan-4-yl 2,3-dimethyloxirane-2-carboxylate is found in Eupatorium chinense. Based on a literature review very few articles have been published on Eupachinilide G.
