Common Name3,4a-dimethyl-4-[(2-methylbut-2-enoyl)oxy]-4h,5h,6h,7h,8h,8ah,9h-naphtho[2,3-b]furan-5-carboxylic acid
Description3,4A-dimethyl-4-[(2-methylbut-2-enoyl)oxy]-4H,4aH,5H,6H,7H,8H,8aH,9H-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. 3,4a-dimethyl-4-[(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. 3,4A-dimethyl-4-[(2-methylbut-2-enoyl)oxy]-4H,4aH,5H,6H,7H,8H,8aH,9H-naphtho[2,3-b]furan-5-carboxylic acid is an extremely weak basic (essentially neutral) compound (based on its pKa).
