Synthetic Approaches to Chlorinated 5-Hydroxy-5-Methyl-2-Furanones
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.

NEW REACTIONS OF 4,5-DICHLORO-2-DICHLOROMETHYLENE-4-CYCLOPENTENE-1,3-DIONE
The reaction of 4,5-dichloro-2-dichloromethylene-4-cyclopentene-1,3-dione with DMFA gives a high yield of 2,3-dichloro-5-(dimethyliminiomethyl)-2-cyclopentene-1,4-dione. 2,3-Dichloro-5,5-bismethylthio-2-cyclopentene-1,4-dione was isolated as a result of the analogous reaction with DMSO.A reaction mechanism involving diketocarbene is proposed.
