(2r,3r,3as,4r,6s,7r,12r,13ar)-2,3,4,6,13a-pentakis(acetyloxy)-2,9,9,12-tetramethyl-5-methylidene-8,13-dioxo-1h,3h,3ah,4h,6h,7h,12h-cyclopenta[12]annulen-7-yl 2-methylpropanoate

Description

MEGxp0_000276 belongs to the class of organic compounds known as jatrophane and cyclojatrophane diterpenoids. These are diterpenoids with a structure based on the jatrophane or the 9,13-jatrophane skeleton. Jatrophane can be derived from casbane by 6,10-cyclization and opening of the cyclopropane. Cyclojatrophane diterpenoids are based on the 9,13-cyclization of the jatrophane skeleton yields the 9,13-cyclojatrophane skeleton. (2r,3r,3as,4r,6s,7r,12r,13ar)-2,3,4,6,13a-pentakis(acetyloxy)-2,9,9,12-tetramethyl-5-methylidene-8,13-dioxo-1h,3h,3ah,4h,6h,7h,12h-cyclopenta[12]annulen-7-yl 2-methylpropanoate is found in Euphorbia paralias. Based on a literature review very few articles have been published on MEGxp0_000276.

Chemical Taxonomy

Description

Belongs to the class of organic compounds known as jatrophane and cyclojatrophane diterpenoids. These are diterpenoids with a structure based on the jatrophane or the 9,13-jatrophane skeleton. Jatrophane can be derived from casbane by 6,10-cyclization and opening of the cyclopropane. Cyclojatrophane diterpenoids are based on the 9,13-cyclization of the jatrophane skeleton yields the 9,13-cyclojatrophane skeleton.
