Article

The synthesis of 4,3-dihydro, 5-phenyl,4-(1 H-indolyl)-3-(3′4′5′-substituted pyrazole/oxazole) derivatives from [(3-phenyl-4,5-dihydro-5-substituted phenyl)-1 H-pyrazole/oxazole]-1 H-indolyl and [(3-phenyl-4,5-dihydro-5-substituted phenyl-1 H-pyrazole/oxazole]-1 H-(3-substituted indolyl) is described. The structures of the synthesized compounds have been established by elemental analysis and IR, 1 H NMR, and mass spectroscopy. The synthesized compounds have been tested against reference microbial strains, and most tests showed excellent results.

Key words

Antibacterial activity antifungal activity chalcone precursor isoxazole synthesis pyrazole synthesis
