Common Name8-hydroxy-3-isopropyl-5a,8-dimethyl-1h,2h,3h,4h,5h,6h,7h,10ah,10bh-cyclohepta[e]indene-3a-carboxylic acid
Description8-Hydroxy-5a,8-dimethyl-3-(propan-2-yl)-1H,2H,3H,3aH,4H,5H,5aH,6H,7H,8H,10aH,10bH-cyclohepta[e]indene-3a-carboxylic acid belongs to the class of organic compounds known as valparane and mulinane diterpenoids. These are diterpenoids with a structure based on either the valparane or mulinane skeleton. Valparane and mulinane are tricyclic compounds containing a tetradecahydrocyclohepta[e]indene skeleton. Valparane carries a 1-methylethyl at the 3-position, as well as three methyl groups at the 5a-, 8-, and 10b-position of the ring system. Mulinane carries a 1-methylethyl at the 3-position, as well as three methyl groups at the 3a-, 5a-, and 8-position of the ring system. 8-hydroxy-3-isopropyl-5a,8-dimethyl-1h,2h,3h,4h,5h,6h,7h,10ah,10bh-cyclohepta[e]indene-3a-carboxylic acid is found in Azorella madreporica and Azorella prolifera. 8-Hydroxy-5a,8-dimethyl-3-(propan-2-yl)-1H,2H,3H,3aH,4H,5H,5aH,6H,7H,8H,10aH,10bH-cyclohepta[e]indene-3a-carboxylic acid is an extremely weak basic (essentially neutral) compound (based on its pKa).
