HETEROCYCLES FROM CARBOHYDRATE PRECURSORS. XXXIII. THE SCOPE OF THE REACTIONS OF HYDRAZINES AND HYDRAZONES: DEHYDRATIVE CYCLISATIONS OF SOME NITROGEN DERIVATIVES OF DEHYDRO-L-ASCORBIC ACID

-1H-quinoxalin-2-one was prepared from dehydro-L-ascorbic acid (L-threo-2,3-hexodiulosonic-1,4-lactone).Its dehydrative cyclisation gave 3--1H-quinoxalin-2-one or 1-(3-chlorophenyl)-3-(L-threo-1,2,3-trihydroxypropyl)flavazole, according to the method used for the dehydration.Acetylation and benzoylation of the flavazole afforded 3-(tri-O-acetyl-L-threo-1,2,3-trihydroxypropyl)-1-(3-chlorophenyl)flavazole and 3-(tri-O-benzoyl-L-threo-1,2,3-trihydroxypropyl)-1-(3-chlorophenyl)flavazole, respectively.N-Methylation and periodate oxidation of the starting hydrazone gave 3--1-methylquinoxalin-2-one and 2-(3-chlorophenylhydrazono)-2-(2-oxo-1H-quinoxalin-3-yl)acetaldehyde.
