Natural Product Identification

Common Name

5-hydroxy-1,8a-dimethyl-6-oxo-7-(propan-2-ylidene)-hexahydro-1h-naphthalen-2-yl 5-methyldodeca-2,4,6-trienoate

Description

5-Hydroxy-1,8a-dimethyl-6-oxo-7-(propan-2-ylidene)-decahydronaphthalen-2-yl 5-methyldodeca-2,4,6-trienoate 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. 5-Hydroxy-1,8a-dimethyl-6-oxo-7-(propan-2-ylidene)-decahydronaphthalen-2-yl 5-methyldodeca-2,4,6-trienoate 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.
