What is Synthesis, Characterization Of Some 1-(2-hydroxy-phenyl)-3-(1-phenyl-3-thiophen-2-yl-1h-pyrazol-4-yl)-propenone, 3-chloro-2-(1-phenyl-3-thiophen-2-yl-1h-pyrazol-4-yl)-chromon-4-one And 2-(1'-phenyl-3'-thiophen-2-yl-3,4-dihydro-2h,1h'-[3,4]bipyrazol-5-yl)-phenol about?

Base catalyzed condensation of 1 with 2 gives compound 3 [l-(2-hydroxy-phenyl)-3-(l-phenyl-3-thiophen-2yl-lH-pyrazol-4-yl)-propenone], 3 on oxidative cyclization with DMSO-CUC1 2 gives 3-chloro-2-(l-phenyl-3-thiophen-2-yl-1 H-pyrazol-4-yl)-chromon-4-one 4. 3 on condensation with hydrazine hydrate gives 2-(l '-phenyl-3'-thiophen-2-yI-3,4dihydro-2H,lH'-[3,4]bipyrazol-5-yl)-phenol 5. The products 3, 4 and 5 were characterized by IR, 'H NMR and mass spectroscopy.
