2-Fluoroalkoxyenaminones were synthesized from alpha-fluoroalkoxyacetophenones and dimethylformamide dimethylacetal in almost quantitative yields. These compounds are promising aliphatic precursors for fluoroalkoxy containing heterocycles construction that was proved by reactions with hydrazine, hydroxylamine and amidines yielding corresponding pyrazoles, isoxazoles and pyrimidines.
