Furo[3,4-b]chromones, and not pyrano[3,4-b]chromones, are obtained by the reaction of 3-formylchromones with isocyanides
The reaction of formylchromones with alkyl isocyanides was reinvestigated. In earlier reports from other research groups, two different structures were proposed for the products of this reaction. Herein, we provide unambiguous evidence that these products
