Syntheses and characterization of pyrrole containing hydrazones

Author(s): Sunil Kumar, Dinesh Kumar

Pyrrole hydrazones have been extensively studied as a building blocks for the synthesis of various representatives for pyrrole family,especially condenced heterocycles genetically related to pyrrole.Pyrrole hydrazones bearing functional groups on the double bond (or those without them) are highly reactive starting compounds for the targeted synthesis of conjugated and fused heterocycles similar to natural pyrrole assemblies. In the present work we have synthesized Pyrrole hydrazones by condensation reactions between formyl pyrroles (Pyrrole-2-carboxaldehyde, pyrrole 2, 5- dicarboxaldehyde and 2,4-dimethyl-3-formy-l-5-carbethoxy pyrrole) and different hydrazide.The structure of synthesized compounds was confirmed by spectral (IR,1H NMR) data.
