We describe a convenient and general method for the preparation of 2,3-dihydro-2-nitro-3-phenyl-4H-furo<3,2-c><1>benzopyran-4-ones from 4-hydroxycoumarin and (2-chloro-2-nitroethenyl)benzenes in the presence of potassium fluoride.Using the same starting materials and by replacing potassium fluoride with triethylamine the hitherto unknown 3-phenyl-4H-furo<3,2-c><1>benzopyran-4-ones are obtained in a one-pot procedure.
