Common Name

3,4,5-trimethyl-5h,6h,7h,8h-naphtho[2,3-b]furan-9-yl propanoate

Description

3,4,5-Trimethyl-5H,6H,7H,8H-naphtho[2,3-b]furan-9-yl propanoate 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. 3,4,5-trimethyl-5h,6h,7h,8h-naphtho[2,3-b]furan-9-yl propanoate is found in Senecio lydenburgensis. Based on a literature review very few articles have been published on 3,4,5-trimethyl-5H,6H,7H,8H-naphtho[2,3-b]furan-9-yl propanoate.

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.
