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. Copyright © 1986 Journal of Heterocyclic Chemistry
