Bioinspired Total Synthesis of Polycyclic Natural Products.

Despite the great strides in biopharmaceuticals and monoclonal antibodies today, natural products remain highly attractive as drug candidates. Therefore, building a library of natural products through total synthesis is critically important for drug discovery. This perspective article details the collective total synthesis of polycyclic natural products using "bioinspired reactions" that mimic natural product biosynthesis. It discusses the total syntheses of 20 natural products, including dimeric diketopiperazine alkaloids, monoterpenoid indole alkaloids, and iridoid glycosides, each achieved in fewer than 14 steps starting from commercially available materials.
