Common Name

[(1r,3ar,11r,12ar)-11-(acetyloxy)-1-hydroxy-1-isopropyl-3a,10-dimethyl-2h,3h,4h,7h,8h,11h,12h,12ah-cyclopenta[11]annulen-6-yl]methyl acetate

Description

[(1R,3aR,11R,12aR)-11-(acetyloxy)-1-hydroxy-3a,10-dimethyl-1-(propan-2-yl)-1H,2H,3H,3aH,4H,7H,8H,11H,12H,12aH-cyclopenta[11]annulen-6-yl]methyl acetate belongs to the class of organic compounds known as dolabellane and neodolabellane diterpenoids. These are diterpenoids with a structure based on the dolabellane skeleton (3a,6,10-trimethyl-1-(propan-2-yl)-cyclopenta[11]annulene) or the neodolabellane skeleton. [(1r,3ar,11r,12ar)-11-(acetyloxy)-1-hydroxy-1-isopropyl-3a,10-dimethyl-2h,3h,4h,7h,8h,11h,12h,12ah-cyclopenta[11]annulen-6-yl]methyl acetate is found in Canistrocarpus cervicornis. Based on a literature review very few articles have been published on [(1R,3aR,11R,12aR)-11-(acetyloxy)-1-hydroxy-3a,10-dimethyl-1-(propan-2-yl)-1H,2H,3H,3aH,4H,7H,8H,11H,12H,12aH-cyclopenta[11]annulen-6-yl]methyl acetate.
