A simple, one‐pot, metal‐free method for the synthesis of 3‐unsubstituted indolizines from readily available (iso)quinolines and propiolates is presented. Employing solvent‐free conditions, the competitive cyclization into 1,2‐disubstituted indolizines was suppressed, allowing remarkable chemoselectivity towards the synthetically valuable C1 mono‐substituted indolizines.
