Common Name(4s,4ar,5s)-3,4a,5-trimethyl-4h,5h,6h,7h,9h-naphtho[2,3-b]furan-4-yl 2-methylpropanoate
DescriptionIsobutyric acid [(4S)-4,4a,5,6,7,9-hexahydro-3,4abeta,5beta-trimethylnaphtho[2,3-b]furan]-4beta-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. (4s,4ar,5s)-3,4a,5-trimethyl-4h,5h,6h,7h,9h-naphtho[2,3-b]furan-4-yl 2-methylpropanoate is found in Jacobaea auricula. Based on a literature review very few articles have been published on Isobutyric acid [(4S)-4,4a,5,6,7,9-hexahydro-3,4abeta,5beta-trimethylnaphtho[2,3-b]furan]-4beta-yl ester.
