Thermal Transformations of Some 3-Acyl-2-oxo-2H-1-benzopyrans with Acid Anhydrides

The reaction of 3-benzoyl- and 3-acetyl-2-oxo-2H-1-benzopyrans (4 and 5) with acid anhydrides in the presence of sodium acetate or triethylamine has been studied.With propionic, butyric and isobutyric acid anhydrides, 4 affords the rearrangement products 6 and 7, dilactones (8) and benzyl esters (9), whereas with acetic anhydride 6a, 10, 11 and 12 are obtained.The reaction of 5 with acetic and propionic acid anhydrides affords 6e, 8f and 9f.Conversion of 9c into different products under acidic conditions has also been studied.
