Figure 6.
FIGURE 6. Bound conformations of saturated and unsaturated IZD-phenyl moieties. a, the relative angle between the unsaturated IZD and phenyl rings of 1 is 70-75°. b, superposition of the unsaturated IZD 1 (stick bonds) and the saturated (S)-IZD-phenyl moiety of 2 (ball-and-stick). Note the phenyl ring and heteroatoms of IZD bind in the same position whether or not the heterocycle is reduced.
