One-pot synthesis of dihydroimidazo- and imidazophenanthridinium salts

By A. D. C. Parenty and L. Cronin

Abstract

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
