Study of the reactions of 3-acetoacetyl-7-methyl-2H,5H-pyrano[4,3-b]pyran-2,5-dione with aromatic amines

The reactions of 3‐acetoacetyl‐7‐methyl‐2H,5H‐pyrano[4,3‐b]pyran‐2,5‐dione with aromatic amines afforded 3‐(arylaminomethylene)‐6‐methylpyran‐2,4‐dione. Our results allowed the correction of the structures reported in the literature for the products of these reactions.
