A straightforward strategy for the synthesis of imidazole-fused benzodiazocine from 1-(2-nitrophenyl)-1H-imidazole-2-carbaldehyde via Morita–Baylis–Hillman reaction followed by reductive intramolecular cyclization is described. Alternatively the Horner–Wadsworth–Emmons reaction of this substrate with triethyl phosphonoacetate yielded (E)-ethyl 3-(1-(2-nitrophenyl)-1H-imidazol-2-yl)acrylate which upon

The invention relates to novel phenyl pyrrole aminoguanidine derivatives modified at the guanidine group. The invention further relates to the use of such phenyl pyrrole aminoguanidine derivatives for the treatment of diseases associated with the melanocortin receptors or related systems, e.g. inflammation and inflammatory conditions. The novel phenyl pyrrole aminoguanidine derivatives of the invention have the general formula (I) and includes tautomeric and isomeric forms thereof, wherein X is (CH2)n and n is 0, 1 or 2.
The present invention relates to phenyl pyrrole aminoguanidine derivatives of the general formula (I): (I) including tautomeric forms thereof, wherein n is 1, 2 or 3; or a pharmaceutically acceptable salt thereof. The present invention further relates to the use of such phenyl pyrrole aminoguanidine derivatives for the treatment of diseases associated with the melanocortin receptors or related systems, e.g. the melanocyte stimulating hormones.
