Azonia Aromatic Cations by Ring-Closing Metathesis: Synthesis ofAzaquinolizinium Cations.
Departamento de Quimica Organica y Quimica Inorganica, Universidad de Alcala , 28805 Alcala de Henares , Spain.
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.
