Common Name

(4s,4as,5s,8ar)-3,4a-dimethyl-4-{[(2z)-2-methylbut-2-enoyl]oxy}-4h,5h,6h,7h,8h,8ah,9h-naphtho[2,3-b]furan-5-carboxylic acid

Description

4Beta-(Angeloyloxy)-3,4abeta-dimethyl-4,4a,5,6,7,8,8abeta,9-octahydronaphtho[2,3-b]furan-5beta-carboxylic acid belongs to the class of organic compounds known as eremophilane, 8,9-secoeremophilane and furoeremophilane sesquiterpenoids. These are sesquiterpenoids with a structure based either on the eremophilane skeleton, its 8,9-seco derivative, or the furoeremophilane skeleton. Eremophilanes have been shown to be derived from eudesmanes by migration of the methyl group at C-10 to C-5. (4s,4as,5s,8ar)-3,4a-dimethyl-4-{[(2z)-2-methylbut-2-enoyl]oxy}-4h,5h,6h,7h,8h,8ah,9h-naphtho[2,3-b]furan-5-carboxylic acid is found in Ligularia hodgsonii and Ligularia vellerea. Based on a literature review very few articles have been published on 4beta-(Angeloyloxy)-3,4abeta-dimethyl-4,4a,5,6,7,8,8abeta,9-octahydronaphtho[2,3-b]furan-5beta-carboxylic acid.

Chemical Taxonomy

Description

Belongs to the class of organic compounds known as eremophilane, 8,9-secoeremophilane and furoeremophilane sesquiterpenoids. These are sesquiterpenoids with a structure based either on the eremophilane skeleton, its 8,9-seco derivative, or the furoeremophilane skeleton. Eremophilanes have been shown to be derived from eudesmanes by migration of the methyl group at C-10 to C-5.
