Abstract
A new approach for the synthesis of the 1‐azaquinolizinium (pyrimido[1,2‐a]pyrimidin‐5‐ium) heterocycle and some simple derivatives is described. This strategy, based on an unprecedented ring‐closing metathesis (RCM) reaction to construct the pyrimidinium ring, was also applied to the first reported synthesis for the benzo‐1‐azaquinolizinium (pyrimido[2,1‐a]isoquinolinium) cation.
