Figure 9
Core structures for the database survey; (a) tricyclo[9.3.1.0^3,8]pentadecane (taxane) with ring labelling (U: an upper cyclohexane, M: a middle cyclooctane and L: a lower cyclohexane) and its (b) 10-acetoxy-8,12,15,15-tetramethyl derivative, (c) tetracyclo[12.3.1.0^1,5.0^6,11]octadecane as a the main framework of the title compound, and its (d) 15-ene, (e) 14-ene and (e) 14,16-diene derivatives. Ring-fusion geometries in the related structures are similar to the title compound, as syn-UM and anti-ML.
