| Description | (4AS,5S)-3-[(2S,5R,6R,7R)-6-hydroxy-2,7,13,15-tetramethyl-8,11-dioxatetracyclo[7.6.1.0⁵,¹⁶.0¹⁰,¹⁴]Hexadeca-1(15),9(16),10(14),12-tetraen-7-yl]-4a,5-dimethyl-2,4a,5,6,7,8-hexahydronaphthalen-2-one 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. virgaurin C is found in Ligularia virgaurea. virgaurin C was first documented in 2012 (Saito, Y., et al.). Based on a literature review very few articles have been published on (4aS,5S)-3-[(2S,5R,6R,7R)-6-hydroxy-2,7,13,15-tetramethyl-8,11-dioxatetracyclo[7.6.1.0⁵,¹⁶.0¹⁰,¹⁴]Hexadeca-1(15),9(16),10(14),12-tetraen-7-yl]-4a,5-dimethyl-2,4a,5,6,7,8-hexahydronaphthalen-2-one. |
