“…When the reaction was repeated using ethanol as solvent rather glacial acetic acid, compound 3a was obtained in high yield (92%) (Scheme 2). Pyrazolines 3b and 3d were obtained by reaction of compounds 2b and 2c respectively with hydrazine hydrate in ethanol using the same procedure given for compound 3a [43]. …”

“…These derivatives were synthesized according to procedure described in reference [11][12][13][14]. A mixture of 2-acetylfuran or 2-acetylpyrrol (0.004 mol), aromatic aldehyde (0.004 mol), and some pellets of solid NaOH in 20 mL of ethanol was stirred at room temperature for 6 h. The resulting solid was washed, dried, and crystallized from ethanol (Scheme 1).…”

KEYWORDS(E)-Chalcone derivatives were synthesized by the Claisen-Schmidt condensation of aromatic aldehydes with methyl ketones. 5-Arylfuran-2-carboxaldehydes (1a-b) were synthesized by Meerwein´s method and condensed with 2-acetylpyrole or 2-acetylfuran to produce the new chalcone derivatives (2a-d). The new chalcones were characterized using FT-IR and GC-MS. The synthesized compounds were also screened against some bacterial species to evaluate their activity as promising antibacterial agents.
