    Description / Table of Contents: Analysis of the 1H NMR spectra of 1,4:3,6-bis (thioanhydro)-D-iditol derivatives (1a to 1c) led to the prediction of the dominant conformations. The configuration and conformation of the symmetric (3) and asymmetric (4) disulphoxides as well as that of the disulphone (5), obtained by oxidation of the 2,5-di-O-acetyl-1,4:3,6-bis(thioanhydro)-D-iditol (1b) was also determined.
    Notes: Die dominierende Konformation einiger 1,4:3,6-bis(Thioanhydro)-D-idit Derivate (1a bis 1c) wurde durch 1H NMR Untersuchungen bestimmt. Weiterhin konnte auch die Konfiguration und Konformation des durch Oxydation aus 2,5-Di-O-acetyl-1,4:3,6-bis(thioanhydro)-D-idit (1b) hergestellten symmetrischen (3) und asymmetrischen (4) Disulfoxyds, sowohl die des Disulfons (5) aufgeklärt werden.

    Notes: Conformational studies of acetylated open chain hexitol derivatives, possessing similar structures but differing in their configuration have been made by analysing their NMR spectra. It is shown, that the carbon chain of all three (manno-, ido-and gluco-) isomers is present in a non planar non zig-zag conformation, containing the acetoxy groups at C-3 and C-4 in a trans relation.

    Notes: Mass spectrometric investigations of α,δ diols and their halogenated derivatives revealed the necessity of postulating a mechanism for both their elimination of water and of haloid acid. This mechanism proceeding via a transition state of larger ring-size than described for similar monofunctional aliphatic compounds was confirmed by deuterium labelling.
