Neuartige discotisch-flüssigkristalline, polare Monothioscyllitol-Derivate [1,2] / Novel Discotic Liquid Crystalline, Polar Monothioscyllitol Derivatives [1,2]
Zeitschrift für Naturforschung. B, A journal of chemical sciences
3-5 On the basis of an improved synthesis of the 1,3,4,5,6-pentaacetate of myo-inositol, now available in only one step from that cyclitol in yields up to 90%, we prepared various derivatives of 1-deoxy-1-mercapto-scyllo-inositol (monothioscyllitol) via the mesylate 1 a or the trifluoromesylate 1 b , respectively. The non-centrosymmtric disc-shaped thioethers 3a-h as well as their S,S-dioxides 4a-h and the S-oxide 5f exhibit thermotropic discotic mesophases over wide temperature ranges.
