Figure 7
Core structures for database survey; tricyclo[9.3.1.0^3,8]pentadecane (taxane) and its (a) 11-ene derivative, (b) 2,4-dioxatetracyclo[12.3.1.0^1,5.0^6,11]octadec-14-ene as the main frame of the title compound with ring-labelling, and its (c) regioisomer of olefin, (d) 16,17-dehydro or (e) 8,9-dehydro derivatives. The geometries of ring-fusion are similar to the title compound in every related structures, as syn-AB, anti-BC and anti-BD.
