The structure of dehydro-L-ascorbic acid phenylosazone
Abstract
Dehydro-L-ascorbic acid phenylosazone has been examined spectroscopically and found to be 2,3-dideoxy-3-phenylazo-2-phenylhydrazino-L-threo-hex-2-enone-1,4-lactone. Some differences in its behaviour compared to D-glucose phenylosazone are explained on the basis of this structure.
