In an effort to develop new antimicrobial agents, a series of chalconederivatives, 3-60, were prepared by Claisen-Schmidt condensation of appropriate acetophenones and 2-furyl methyl ketones with appropriate aromatic aldehydes, furfural, and thiophene-2-carbaldehyde in an aqueous solution of NaOH and EtOH at room temperature. The synthesized compounds were characterized by means of their IR- and NMR-spectral

(E)‐1‐heteroaryl‐3‐arylpropen‐1‐ones. The 13C chemicalshift 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 chemicalshift values (δC) of the chalcone derivatives with the Hammett σ values. The chemicalshift values of the β‐C of the heterocyclic compounds

1-Acetyl-, 1-propionyl- and 1-phenyl-3,5-diaryl-2-pyrazolines have been synthesized by the reaction of the appropriate α,β-unsaturatedketones with hydrazine or phenylhydrazine in hot acetic acid or propionic acid. Structures of all new 2-pyrazolines 16-40 have been elucidated by microanalyses, 1H and 13C nmr spectroscopies.
通过适当的α,β-不饱和酮与肼或苯肼在热乙酸或丙酸中的反应,已经合成了1-乙酰基,1-丙酰基-和1-苯基-3,5-二芳基-2-吡唑啉。所有新的2-吡唑啉16-40的结构已通过微量分析,1 H和13 C nmr光谱学得以阐明。
