Figure 6
Core structures for database survey; tricyclo[9.3.1.0^3,8]pentadecane (taxane) and its (a) 11-ene and (b) 13-ene derivatives, (c) bicyclo[5.3.1]undeca-7,9-diene, (d) the tetracyclic core of the title compound with ring labelling and (e) its dihydro derivative and (f) the regioisomer of olefin. The ring-fusion geometries are similar to the title compound in each of the related structures, as cis-AB, trans-BC and trans-BD.
