A practical method for the synthesis of 3,5-disubstituted isoxazoles via cyclization of β-fluoro enones with sodium azide was disclosed. Density functional theory (DFT) calculation indicated that both (1) the azirine formation followed by intramolecular rearrangement and (2) direct enolate O-attack via 5-exo-trig cyclization of vinyl azide were possible for the isoxazole formation.

Reaction between aryl 1,3-diketoesters 2a-e and hydroxylamine hydrochloride has been investigated under different experimental conditions. Whereas acid conditions gave principally 3,5-isoxazole esters (3a-e), reactions under neutral and basic conditions l
