Villanovane, atisane, trachylobane or helvifulvane diterpenoids

Diterpenoids with a structure based on the villanovane, atisane, trachylobane or helvifulvane skeleton. The astisane and atisane skeletons arise from the rearrangement of the beyerane cation intermediate. The trachylobane and helvifulvane skeletons are formed by rearrangement of the beyerane cation intermediate followed by cyclisation.
