Condensation of 4-hydroxy-3,3-dimethyl-2-butanone and 1-acetyl-1-hydroxymethylcyclohexane with trifluoroacetonitrile and 1,1,2,2-tetrafluoropropionitrile in the presence of N-ethylanilinomagnesium bromide affords the corresponding β-hydroxyoxoenamines. The acidic hydrolysis of these compounds results in 5,5-dialkyl-2-hydroxy-2-polyfluoroalkyl-4-tetrahydropyrones which have been dehydrated into 5,5-dialkyl-2-polyfluoroalkyl-4-dihydropyrones.
