| Common Name | (1r,2r,8ar)-1,8a-dimethyl-6-oxo-7-(propan-2-ylidene)-2,3,4,8-tetrahydro-1h-naphthalen-2-yl 2-methylprop-2-enoate |

| Description | 2-Methylpropenoic acid [(4aR)-3-isopropylidene-4abeta,5beta-dimethyl-2,3,4,4a,5,6,7,8-octahydro-2-oxonaphthalen]-6alpha-yl ester 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. (1r,2r,8ar)-1,8a-dimethyl-6-oxo-7-(propan-2-ylidene)-2,3,4,8-tetrahydro-1h-naphthalen-2-yl 2-methylprop-2-enoate is found in Petasites hybridus. Based on a literature review very few articles have been published on 2-Methylpropenoic acid [(4aR)-3-isopropylidene-4abeta,5beta-dimethyl-2,3,4,4a,5,6,7,8-octahydro-2-oxonaphthalen]-6alpha-yl ester. |
