Synthesis and antibacterial activity of 3-aryl-4-formyl-1-[3-(3-chlorophenyl)-1,8-naphthyridin-2-yl]pyrazoles
Condensation of 2-hydrazino-3-(3-chlorophenyl)-1,8-naphthyridine 2 with different acetophenones in methanol containing a catalytic amount of glacial acetic acid affords the corresponding acetophenone 3-(3-chlorophenyl)-1,8-naphthyridin-2-ylhydrazones 3 in excellent yields. The hydrazones 3 when subjected to the Vilsmeier-Haack reaction with POCl3-DMF gives 3-aryl-4-formyl-1-[3-(3-chlorophenyl)-1,8-naphthyridin-2-yl]pyrazoles 4 in good yields. The structural assignments to compounds 3 and 4 arc based on their elemental analyses and spectral data. Compounds 4 have been tested for their antibacterial activity.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 1631-25-0. Category: naphthyridines.
