The first total synthesis of speradine C has been achieved in only ten steps from a commercially available 4‐bromoindole. Salient features of the work are the formation of four rings through three cyclizations, namely a bioinspired [3+2] annulation to form the C/D rings, an NCS‐mediated oxidation to construct the E ring, and a Ru‐catalyzed ketohydroxylation to assemble the F ring. This work highlights how strategic ring constructions can streamline the synthesis of polycyclic compounds.
