An efficient unprecedented synthesis of novel functionalized imidazoles from secondary amino-N-carbothioic acid (phenyl-p-tolylimino-methyl)amides and dimethyl acetylenedicarboxylate

The synthesis of functionalized imidazoles in a single-pot from the reactions of secondary amino-N-carbothioic acid (phenyl-p-tolylimino-methyl)amides with dimethyl acetylenedicarboxylate is reported. A plausible mechanistic pathway for the formation of the imidazoles is proposed.
