A new entry to C‐5 substituted 4‐hydroxy‐6‐methyl‐2‐pyrones has been achieved. The best conditions to prepare the monobromo and the dibromo derivatives at C‐3 and the C‐6 methyl group of the title pyrone have been defined. The synthetic applicability of the phosphonium salts at CH3‐C‐6 of both 4‐methoxy‐6‐methyl‐2‐pyrone, 5, and dehydroacetic acid, 2, has also been evaluated.
