Common Name

(4r,4ar,5s)-4,9-dihydroxy-3,4a-dimethyl-4h,5h,6h,7h,8h-naphtho[2,3-b]furan-5-carboxylic acid

Description

(4R,4aR,5S)-4,9-dihydroxy-3,4a-dimethyl-4H,4aH,5H,6H,7H,8H-naphtho[2,3-b]furan-5-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. (4r,4ar,5s)-4,9-dihydroxy-3,4a-dimethyl-4h,5h,6h,7h,8h-naphtho[2,3-b]furan-5-carboxylic acid is found in Ligularia intermedia. Based on a literature review very few articles have been published on (4R,4aR,5S)-4,9-dihydroxy-3,4a-dimethyl-4H,4aH,5H,6H,7H,8H-naphtho[2,3-b]furan-5-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.
