Twenty‐five different brominated derivatives of 4‐hydroxy‐6‐methyl‐2‐pyrone (triacetic acid lactone) and 3‐acetyl‐4‐hydroxy‐6‐methyl‐2‐pyrone (dehydroacetic acid) have been prepared. Fifteen derivatives have not been previously described and the preparations of a few known products have been improved. Bromination at C‐3, C‐5, methyl group at C‐6 and deacetylations at C‐3 have been the types of reactions used. Copyright © 1985 Journal of Heterocyclic Chemistry
