A Novel Synthesis for New Substituted Imidazoles

MMH owes him a personal debt of deep gartitude for his encourgments and friendships. The addition of dimethyl acethylendicarboxylate (DMAD) to thiosemicarbazone and guanylhydrazone of aldehydes afforded compoundes which were characterized to be new substituted imidazoles. Their structures were determined by 1H NMR, IR, mass spectra and elemental analyses
