Synthesis and characterisation of some 2-[2(1-phenyl-3-thiophen-2-yl-1H- pyrazol-4-yl)]-vinyl chromene-4-ones

β-Diketone 5 is prepared by BakerVenkatram'an transformation of the ester 4, which is obtained by esterification of the acrylic acid 2 with 2-hydroxyacetophenone 3. The acid catalyzed cyclization of 5 yielded 2-[2(1-phenyl-3-thiophen-2-yl-1H-pyrazol-4-yl)
