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.
