| Amphiphilic Carbohydrate-Based Mesogens, 12 [1] High-Yield Synthesis of Mesogenic l-O-Alkanoyl-D/L-Xylitols  | | | | Abstract
| The equilibrium mixture of 1,2:3,4-and l,3:2,4-di-0-ethylboranediyl-D /L-xylitols 1 and 1' obtained on reaction o f three equivalents of xylitol with two equivalents of triethylboroxin, reacts with alkanoyl chlorides (heptanoyl-dodecanoyl) to give equilibrium mixtures of the O-ethylboranediyl protected l-O-alkanoyl-D.L-xylitols 2,2' after vacuum distillation. Depro tection of the latter affords the title amphiphilic esters 3 which melt to give the smectic A liquid-crystalline phase. | | | |
