Abstract

Reactions of 4-aryl-6-trifluoromethyl-2H-pyran-2-ones with sodium hydroxide followed by acidification provided the respective 6-hydroxy-5,6-dihydro derivatives, while the reactions of 4-aryl-6-trifluoromethyl-2H-pyran-2-ones with hydrazine and hydroxylamine were accompanied by rearrangement to N-substituted 6-hydroxy-5,6-dihydro-2-pyridones.
