Abstract
- The carbonitrile compound, 2-amino-5-oxo-4-propyl-4,5-dihydropyrano[3,2- c]chromene-3-carbonitrile was synthesized, in 83% yield, by one-pot multicomponent reaction of butyraldehyde, malononitrile and 4-hydroxycoumarin using 10 mol% urea as an organo-catalyst at room temperature, and its crystal structure was determined by X-ray diffraction technique. The crystals are triclinic, a = 7.7379(5), b = 8.7520(6), c = 11.6589(5) Å, α = 96.668(4)°, β = 100.033(4)°, γ = 112.547(6)°, Z = 2, sp. gr. P. Both pyran rings in the molecule adopt a boat conformation. The crystal structure is stabilized by N-H···O and N-H···N hydrogen bonds. [ABSTRACT FROM AUTHOR]
