Abstract
The structure of 3-acetoacetyl-2-chromenone has been definitely assigned to the product resulting from the reaction of 4-hydroxy-6-methyl-2-pyrone, 1, with 2-hydroxybenzaldehyde. Also, the reaction of the pyrone 1 with pentane-2,4-dione in a 2:1 molar ratio gives 3,6,9,12-tetramethyl-1H,6H,7H,12H-6,12-methanodypirano[4,3-b:4,3-f]dioxocin-1,7-dione. X-Ray analyses of both products are presented.
