A carbocyclic analogue of distamycin was obtained, in which the N-methylpyrrole rings were substituted by disubstituted benzene rings. Additionally, N-chloro- or N-bromoacetyl groups, displaying alkylating properties, were introduced. The synthesis, starting from 3,5-dinitrobenzoyl chloride, consisted of five stages.
