SYNTHESIS AND REACTIONS OF SOME HYDRAZONES OF DEHYDRO-L-ASCORBIC ACID

L-threo-2,3-Hexodiulosono-1,4-lactone 2-(3-chlorophenylhydrazone) and 4-(2-acetoxyethylidene)-4-hydroxy-2,3-dioxobutano-1,4-lactone 2-(3-chlorophenylhydrazone) were prepared.The two geometric isomers of the corresponding bis(hydrazone) underwent an intramolecular rearrangement to 1-(3-chlorophenyl)-3-(L-threo-glycerol-1-yl)-4,5-pyrazoledione 4-(3-chlorophenylhydrazone), which gave a tri-O-acetyl derivative upon acetylation and the anticipated formyl derivative upon periodate oxidation.Oxidation of the bis(hydrazone) with cupric chloride afforded the bicyclic compound 3,6-anhydro-3-C-(3-chlorophenylazo)-L-xylo-2-hexulosono-1,4-lactone 2-(3-chlorophenylhydrazone), whose acetylation afforded the mono-O-acetyl derivative.
