In this paper, some chalcone derivatives (C1, C2) were synthesized based on the reaction of equal amount of substituted acetophenone and substituted banzaldehyde in basic medium. Oxazine and thiazine derivatives were prepared from the reaction of chalcones (C1-C2) with urea and thiourea respectively in a basic medium. Pyrazole derivatives were prepared based on the reaction of chalcones with hydrazine mono hydrate or phenyl hydrazine in the presence of glacial acetic acid as a catalyst. The new synthesized compounds were identified using various physical techniques like1 H-NMR and FT-IR spectra.

A range of optically active pyrrole monomers have been synthesized in which a chiral sub- stituent is covalently bonded either to the pyrrole N or C3 ring position, namely (–)-(1R)-4-methyl-N-(1-phenylethyl)pyrrole-3-carboxamide, (+)-(1S)-4-methyl-N-(1-phenylethyl)pyrrole-3-carboxamide, (–)-(1R)-4-methyl-N-(1-naphthylethyl)pyrrole-3-carboxamide, (+)-(1S)-4-methyl-N-(1-naphthylethyl)pyrrole-3-carboxamide, (+)-(2S)-2-(1H-pyrrol-1-yl)propionic acid, (+)-(1S)-N-(1-phenyl-ethyl)pyrrole, and (–)-(1R)-N-(1-phenylethyl)pyrrole. Their chiroptical properties have been established by circular dichroism spectroscopy. Electropolymerization of the three N-substituted pyrrole monomers provided films of chiral conducting polymers, whose electrical and spectroscopic properties are described. Although oxidation of the C3 substituted pyrrole monomers was also facile, electrodeposition was poor and films of the associated polymers could not be obtained.
