The sponge-derived alkaloid dibromoagelaspongin was prepared from a dihydrooroidin derivative by exploiting the Pummerer reaction twice in succession. Oxidative cyclization of the substrate’s pyrrole-2-carboxamide function into the imidazole moiety was achieved in a regiospecific manner to establish both C−N bonds to C(6) of the target.
