A new cascade double N-annulation method has been developed for the synthesis of benzoquinolizinium salts. The process takes place between allylamines, internal alkynes, and HBF4 in the presence of Rh(III)/Cu(II) complexes and leads to formation of multisubstituted benzoquinolizinium salts. Importantly, the resulting benzoquinolizinium salts serve as fluorescent materials whose emission wavelengths can be tuned by selection of appropriate substituents.
