Condensation of 4-hydroxy-3,3-dimethyl- and 4-hydroxy-3,3-pentamethylenebutan-2-ones with ethyl trifluoroacetate in the presence of LiH in hexane afforded 2-hydroxy-5,5-dimethyl- and 2-hydroxy-5,5-pentamethylene-2-trifluoromethyltetrahydro-4-pyranones, whose behavior in reactions with N-nucleophiles is analogous to that of unsymmetrical polyfluorinated beta-diketones.
