  Enantiopure Trioxadecalin Derived Liquid Crystals: Influence of the Nature of the Phenyl Substituent on the Mesogenic Properties

  摘要：

  Reaction of pseudo-glucal 1 with Grignard reagents derived from 1-bromo-4(trimethylsilyloxy)benzene, 1-bromo-4-methoxybenzene, 1-bromo-4-methoxymethoxybenzene, 1-bromo-4-dimethylaminobenzene, in the presence of a catalytic amount of NiCl2(dppe), gives the corresponding unsaturated beta-C-aryl glycosides 2. Desilylation and hydrogenation of 2 leads to beta-C-aryl glycosides 4, which can be used as chiral precursor compounds in the synthesis of chiral liquid crystals. Combination of 4 with arylaldehydes leads to compounds 5-7, whereas reaction with p-alkoxysubstituted phenylboronic acids gives the trioxaboradecalins 8-11. The mesogenic properties of these compounds are strongly influenced by the nature of the substituent on the phenyl ring in the molecule.
