Tandem reactions using base‐promoted processes have been developed for the synthesis of xanthone and chromone derivatives. The first examples of base‐promoted insertion reactions of isolated carbon–carbon triple bonds into carbon–carbon σ‐bonds have been reported. Using these approaches, polycyclic structures can be prepared. This reaction has the potential to become a general synthetic protocol for
