Cyclitol osazones

Cyclitol osazones consume the expected amount of periodate (three molar equivalents per mole), but the presumed product, 2,3-bis(phenylhydra-zono)succindialdehyde (XCVII), cyclizes to the pyrazole XCVIII.212 The... 

Magasanik and Chargaff286,287 have shown that cyclitol osazones, for example, lD-c/n ro-inositol phenylosazone (94), consume the expected amount of periodate... 

The chemistry of carba sugars is quite similar to that of cyclitols both groups lack the latent carbonyl groups of their saccharide counterparts, and therefore fail to exhibit many of the characteristic properties of monosaccharides. Thus carba sugars and cyclitols do not form hydrazones or osazones, nor do they mutarotate, or reduce heavy-metal salts in base, in contrast to their oxidation products, the inososes.
