Palabras clave: Synthetic methods; Nitrogen heterocycles; Metathesis; Benzo[a]Dquinolizinium salts
Resumen
Benzo[a]Dquinolizinium salts have been synthesized through ring-closing metathesis reactions of 1-butenyl-2-vinylisoquinolinium, 2-butenyl-1-vinylisoquinolinium and 2-styryl-1-vinylpyridinium salts in the presence of Grubbs and Hoveyda?Grubbs catalysts. The results show that the lastapproach is the most efficient for the preparation of this heteroaromatic tricyclic system and several previously unknown derivatives have been prepared.
