The totalsynthesis of the human telomeraseinhibitor γ‐rubromycin in its racemic form was accomplished in 3.8 % overall yield. The key feature of this synthesis is an efficient acid‐catalyzed spiroketalization for the construction of the spiroketal core. The required electronically well‐balanced spiroketal precursor was obtained by the convergent assembly of a naphthyl‐substituted aldehyde, an α‐
