Interpretive Summary:

Technical Abstract: Long chain fatty esters, derived from vegetable oils, are of interest as renewable raw materials. These fatty compounds can be functionalized at the ester site to give new long- chain compounds containing the heterocyclic isoxazole ring. Here we report on the successful one-pot condensation of fatty esters, such as methyl oleate, linoleate, stearate, palmitate, and brassylate, with a metallated imine followed by reaction with hydroxylamine and dehydration to give lipid isoxazole heterocycles in good yields. The isoxazole ring represents a versatile synthetic intermediate, and ring opening reactions of the lipid isoxazoles were examined to give fatty compounds containing a beta-aminoenones and beta- diketones. The isoxazoles and their ring-opened compounds may have potentially interesting chemical and physical properties and are not easily accessible by other methods.
