Description

Phyllofolactone K belongs to the class of organic compounds known as scalarane sesterterpenoids. These are sesterterpenoids with a structure based on the scalarane backbone. Scalarane is a tetracyclic compound, which is similar the homoandrostane with five methyl groups at the 4-, 4-, 8-, 17-, 17a-positions. (3r,5as,5br,7as,8s,11as,11br,13s,13ar)-8-ethyl-13-(3-hydroxypentanoyl)-3,5b,8,11a,13a-pentamethyl-3h,4h,5h,5ah,6h,7h,7ah,9h,10h,11h,11bh,12h,13h-chryseno[1,2-c]furan-1-one is found in Strepsichordaia aliena. Based on a literature review very few articles have been published on Phyllofolactone K.
