Abstract
Abstract The syntheses of chlorinated 5 - hydroxy- furanones with a mono-, di-, and trichloromethyl group at C-5 are described. The 5-chloromethyl hydroxyfuranones were obtained by chlorination of levulinic acid followed by triethylamine promoted elimination of hydrogen chloride. Hydrolyses of chlorinated 4 - cyclopentene- 1,3 -diones yielded 5-dichloromethyl hydroxyfuranones. The trichloromethyl group was incorporated to maleic anhydride through thermal decomposition of sodium trichloroacetate.
