Two highly efficient and general one-pot annulation reactions are described for the synthesis of dihydroimidazo- and imidazophenanthridinium salts (DIPs + and IPs +). These two methodologies exploit the difference in reactivity between primary amino-based or ammonia nucleophiles and the dielectrophilic starting material, 2-bromoethylphenanthridinium bromide.

A new class of heterocyclic aromatic cation with novel physical properties has been constructed by an unprecedented reaction pathway that proceeds via five spontaneous steps to yield a âsynthonâ that can be further derivatised by a final nucleophilic substitution step.
