, p. 668 - 673 (2019/07/12)
A series of the chalcone derivatives of the five-membered monoheterocyclic compounds, (E)-1-aryl-3-heteroarylpropen-1-ones, were prepared by aldol condensation of the corresponding aldehydes of thiophene, pyrrole, and furan with m- and p-substituted acetophenones. Similar condensation of the acetyl compounds of the heterocycles with m- and p-substituted benzaldehydes gave another series of the chalcone derivatives, (E)-1-heteroaryl-3-arylpropen-1-ones. The 13C chemical shift values (δC) of the chalcone derivatives were determined in order to find if they correlated with the Hammett σ values. A good correlation, especially for the β-C for both series, was found for the 13C chemical shift values (δC) of the chalcone derivatives with the Hammett σ values. The chemical shift values of the β-C of the heterocyclic compounds were plotted against those of the benzene derivatives. The resulting slopes were found to be close to the values of the aromaticity indices.

A series of sulfur-containing heterocyclic pyrazoline derivatives (C1-C18; D1-D9) have been synthesized and purified (all are new except one) to screen for FabH inhibitory activity. Compound C14 showed the most potent biological activity against Escherich
Studies on the nuclear magnetic resonance spectra of (E)-1-Aryl-3-(2- and 3-thienyl)-2-propenones and unique observation of 4J and 5J coupling in their 1H-1H COSY

1H and 13C NMR spectra of series of (E)-1-aryl-(2- and 3-thienyl)-2-propenones, that are aldol condensation products between 2- and 3-thiophenecarbaldehydes and m- and p-substituted acetophenones, were examined to make complete assig
