Common Name

8,8a-dihydroxy-3,4a,5-trimethyl-9-oxo-4h,5h,6h,7h,8h-naphtho[2,3-b]furan-4-yl 2-methylpropanoate

Description

8,8A-dihydroxy-3,4a,5-trimethyl-9-oxo-4H,4aH,5H,6H,7H,8H,8aH,9H-naphtho[2,3-b]furan-4-yl 2-methylpropanoate 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. 8,8a-dihydroxy-3,4a,5-trimethyl-9-oxo-4h,5h,6h,7h,8h-naphtho[2,3-b]furan-4-yl 2-methylpropanoate is found in Ligularia atroviolacea and Ligularia virgaurea. 8,8A-dihydroxy-3,4a,5-trimethyl-9-oxo-4H,4aH,5H,6H,7H,8H,8aH,9H-naphtho[2,3-b]furan-4-yl 2-methylpropanoate is an extremely weak basic (essentially neutral) compound (based on its pKa).

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.
