Alditols, anhydrides

Defaye19 called attention to the fact that the 2,5-anhydro-tri-0-(p-nitrobenzoyl)-D-lyxitol that he prepared is the enantiomorph of Barker and Fletcher s 1,4-anhydro-tri-0-(p-nitrobenzoyl)-L-arabinitol.l4Walden inversion, from two configurationally different sugars have been shown experimentally to possess the same, although enantiomorphic, configuration. 

Tables VI-XI show the physical properties of the alditol anhydrides and certain of their derivatives.

In view of this, a new overview of developments in this area is warranted, especially as no special summary on this subject has been published for some time. A comprehensive article2 in a previous volume of this series appeared in 1950. Subsequently, a brief discussion of 1,4 3,6-dianhydrohexitols was incorporated in a contribution on the stereochemistry of cyclic derivatives of carbohydrates,3 and they were treated exhaustively within a summary of alditol anhydrides that contained tables of physical properties of derivatives.4...
