(E)-1-(3,5-bis(trifluoromethyl)phenyl)-3-(substituted phenyl)prop-2-en-1-one, Urea, KOH and Ethanol.Abstract
A cogent synthesis of completely new compound series of by 6-(3,5-bis(trifluoromethyl)phenyl)-4-(4-chlorophenyl)-3,4-dihydro pyrimidine-2(1H)-one (Biginelli reaction) was achieved by continue heating of (E)-1-(3,5-bis(trifluoromethyl)phenyl)-3-(substituted phenyl)prop-2-en-1-one and urea for 5 hours with 40% KOH and ethyl alcohol. (E)-1-(3,5-bis(trifluoromethyl)phenyl)-3-(substituted phenyl)prop-2-en-1-one is produced by Claisen-Schmidt Condensation. In this condensation 1-(3,5-bis(trifluoromethyl)phenyl)ethanone and different aldehyde are mixed. All the novel compound series were characterized by infrared and 1H nuclear magnetic resonance and mass spectroscopic techniques and by elemental analyses. The newly synthesized compounds were evaluated for their antibacterial and antifungal activity
