摘要
Hassel和Barton成功地研究了环己烷的构象变化,为研究单糖、多糖以及甾体等天然化合物的结构和性质奠定了基础。近年来的研究表明,含环己烷环的液晶化合物中六员环的构型直接影响液晶的性质。例如,反式1-烷基-4-(对-氰基)苯基环已烷可以形成液晶,而顺式异构体分子不能有序排列。De
cis-and trans-1, 4-Di(2-naphthyl) cyclohexanes(DNCH) were synthesized by Frie-del-Crafts alkylation of naphthalene with 1, 4-dibromocyclohexane. The cis- and trans-DNCHisomers were separated by column chromatography. The structures of the isomers were deter-mined by ~1HNMR. ^(13)CNMR and MS.
