A flexible route to analogues of dihydroimidazo[5,1-a]isoquinolines is described. The synthesis hinges on a sequential Ugi coupling, followed by a Bischler–Napieralski reaction to form the imidazole isoquinoline core. This route facilitates the introduction of a range of substitutions throughout the carbon framework.
