Abstract
A series of 2-amino-4-aryl-5-oxo-4,5-dihydropyrano[3,2- c]chromene derivatives has been synthesised by the reaction of 4-hydroxycoumarin and substituted cinnamonitriles catalysed by KF-montmorillonite. The structures were characterised by IR and 1H NMR spectroscopic data and confirmed by X-ray diffraction analysis.

Abstract
The reaction of substituted arylidenemalononitriles and 3-methyl-1-phenyl-2-pyrazolin- 5-one in DMF in the presence of KF-montmorillonite provides a rapid synthesis of 3-methyl-6-amino-5-cyano-4-aryl-1-phenyl-1,4-dihydro-pyrano[2,3-c]pyrazole derivatives.
