The solid-phase synthesis of novel imidazolines and dihydroimidazolylbenzimidazoles is described. Resinbound diamines, derived from resin-bound N-acylated amino acid amides, were cyclized using Vilsmeier reagent to yield imidazolines following cleavage. Similarly, cyclization of resin-bound tetraamines having two secondary amines and an o-dianiline yielded dihydroimidazolylbenzimidazoles following cleavage.
