| Abstract | Base catalyzed condensation of 1 with 2 gives compound 3 [1-(5-fluoro-2-hydroxyphenyl)-3-(1-phenyl-3-aryl-1H-pyrazol-4-yl)-2-propen-1-one]. On oxidative cyclization with DMSO-CuCl 2 3 gives 2-(1-phenyl-3-aryl-1H-pyrazol-4-yl)-3-chloro-6-fluorochromones 4. On cyclization with DMSO-I 2 , 3 gives 2-(1-phenyl-3-aryl-lH-pyrazol-4-yl)- 6-fluorochromones 5. When 3 is heated with hydrazine in dioxane gives 6 [5-(1-phenyl-3-aryl-1H-pyrazol-4-yl)-3-(5-fluoro-2-hydroxyphenyl)-4,5-dihydropyrazolines. The products 3, 4, 5 and 6 are characterized by spectral and elemental analysis. Compounds 3, 4 and 6 are tested for their antimicrobial activities. |
