Abstract :
Condensation of 3-acetyl-2,5-dichlorothiophene with 1- or 2-naphthaldehyde led to theformation of the new chalcones (3a,b) in high yields. The latter chalcones were used as a backbone for the synthesis of substituted 3-(2,5-dichlorothiophen-3-yl)-4,5-dihydro-5-(naphthalen-1 or 2-yl)-1H-pyrazole (4a-h) in good yields. All newly synthesized compounds were characterized by standard spectroscopic techniques. The microbiological activity of these new compounds was investigated against bacteria and fungi. The new compounds showed good to excellent activity against all microbial species used for screening.
