2-[4,9-bis(acetyloxy)-2,6,8,10-tetrahydroxy-1,8a-dimethyl-5-methylidene-2h,3h,4h,4ah,6h,7h,8h,9h,10h-cyclohexa[f]azulen-3a-yl]propan-2-yl acetate

Description

2-[4,9-Bis(acetyloxy)-2,6,8,10-tetrahydroxy-1,8a-dimethyl-5-methylidene-2H,3H,3aH,4H,4aH,5H,6H,7H,8H,8aH,9H,10H-cyclohexa[f]azulen-3a-yl]propan-2-yl acetate belongs to the class of organic compounds known as taxanes and derivatives. These are diterpenoids with a structure based either on the taxane skeleton, or a derivative thereof. In term of phytochemistry, several derivatives of the taxane skeleton exist: 2(3->20)-Abeotaxane, 3,11-cyclotaxane, 11(15->1),11(10->9)-abeotaxane, 3,8-seco-taxane, and 11(15->1)-abeotaxane, among others. More complex skeletons have been found recently, which include the taxane-derived [3.3.3] Propellane ring system. 2-[4,9-bis(acetyloxy)-2,6,8,10-tetrahydroxy-1,8a-dimethyl-5-methylidene-2h,3h,4h,4ah,6h,7h,8h,9h,10h-cyclohexa[f]azulen-3a-yl]propan-2-yl acetate is found in Taxus wallichiana. 2-[4,9-Bis(acetyloxy)-2,6,8,10-tetrahydroxy-1,8a-dimethyl-5-methylidene-2H,3H,3aH,4H,4aH,5H,6H,7H,8H,8aH,9H,10H-cyclohexa[f]azulen-3a-yl]propan-2-yl acetate is an extremely weak basic (essentially neutral) compound (based on its pKa).

Chemical Taxonomy

Description

Belongs to the class of organic compounds known as taxanes and derivatives. These are diterpenoids with a structure based either on the taxane skeleton, or a derivative thereof. In term of phytochemistry, several derivatives of the taxane skeleton exist: 2(3->20)-Abeotaxane, 3,11-cyclotaxane, 11(15->1),11(10->9)-abeotaxane, 3,8-seco-taxane, and 11(15->1)-abeotaxane, among others. More complex skeletons have been found recently, which include the taxane-derived [3.3.3] Propellane ring system.
