| Description | Reiswigin A belongs to the class of organic compounds known as sphenolobane diterpenoids. These are diterpenoids with a structure characterized by a sphenolobane skeleton. They possess a trans-fused hydroazulenoid skeleton as a common structural motif, but differ in configuration at C(9), where a prenyl group is attached. Sphenolobane is also considered an 'extended' daucane skeleton, with a carbon side chain appended onto the cyclopentane ring. (1r,3ar,8ar)-3a,6-dimethyl-1-[(2s)-6-methyl-4-oxoheptan-2-yl]-1,2,3,7,8,8a-hexahydroazulen-4-one is found in Myrmekioderma gyroderma. Based on a literature review very few articles have been published on Reiswigin A. |
