Functionalization at C-5 and at the C-6 Methyl Group of 4-Methoxy-6-methyl-2-pyrone

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.
