Abstract The base‐induced [3+3] annulation reaction of phenacyl phosphonium ylides with cyclopropenones has been proposed. Various polysubstituted 2‐pyrones are achieved in moderate to good yields through C−P bond cleavage and C−O/C−C coupling under simple easy‐to‐operate conditions. synthetic application mechanism have also preliminarily explored gain a deeper understanding this strategy practicality details. This protocol offers an alternative approach for the synthesis useful 2‐pyrone derivatives.
