Reporting in Nature, John Hartwig and coworkers have cracked the case: a mixture of iron (II), a tridentate nitrogen ligand, and a modified Togni reagent reliably functionalize tertiary C-H bonds with an azide(N3 group). The selectivity, yield, and mild conditions match pretty well with White's C-H oxidation, which utilized a similar catalytic manifold.
Hartwig's initial targets for this new reaction include two modified steroids and a gibberellic acid derivative. Sadly, precious few heteroatoms exist in these molecules to gum up the ironworks, but I'm certain they'll address that in the full paper. I'd especially like to point readers to Figure 3, in which the group shows subsequent transformations: heterocycle formation, amine reduction, chemical ligation, and capping with fluorescent tags.
These two reactions together, along with a variety of C-H halogenations and sulfidations, seem to support the growing "oxidase phase" approach to total synthesis. One could imagine that, in a few years, a naked carbon scaffold could be suitably decorated with O, N, S, or X at positions of the scientists' choosing. Wow.
