• sterically congested sesquiterpenoids isolated from the genus Illicium. Illisimonin A stands out as one of the most structurally intricate members of this family, featuring a novel bridged tricyclo[5.2.1.01,5]decane carbon framework designated as the “illisimonane” skeleton. This core ring system is further
