Figure 4. Modular synthesis of trioxacarcin A.

Figure 4

An 11-step synthesis of trioxacarcin A was achieved by the convergent assembly of five modular components of similar structural complexity, each denoted with a colored circle. This strategy provides a general route to analogs with deep-seated structural variations.
