Abstract
Condensation of 4-hydroxy-3,3-dimethyl- and 4-hydroxy-3,3-pentamethyle nebutan-2-ones with ethyl trifluoroacetate in the presence of LiH in h exane afforded 2-hydroxy-5,5-dimethyl- and methylene-2-trifluoromethyl tetrahydro-4-pyranones, whose behavior in reactions with N-nucleophile s is analogous to that of unsymmetrical polyfluorinated beta-diketones .
