  • Diastereo-differentiating cyclopropanation of a chiral enol ether: a simple method for the preparation of optically pure cyclopropyl ethers
    作者:Takashi Sugimura、Masato Yoshikawa、Tohru Futagawa、Akira Tai
    DOI:10.1016/s0040-4020(01)87920-5
    日期:1990.1
    Enol ether of cyclohexanone carrying 2,4-pentanediol(PD) or 2,6- dimethyl-3,5-heptanediol(DMHD) as a chiral auxiliary was subjected to diastereo-differentiating cyclopropanation. The highest diastereomer excess(d.e.) of the product was found to be 95.2% in the case of PD and over 99.5% in the case of DMHD. The enol ethers prepared from various ketones and DMHD were also cyclopropanated in giving cyclopropyl
    将带有2,4-戊二醇(PD)或2,6-二甲基-3,5-庚二醇(DMHD)作为手性助剂的环己酮的烯醇醚进行非对映异构化环丙烷化。发现对于PD而言,产物的最高非对映异构体过量(de)为95.2%,对于DMHD而言,为超过99.5%。还对由各种酮和DMHD制备的烯醇醚进行了环丙烷化反应,制得了几乎100%de的环丙基醚。

    日期:1990.4
    Optically pure 2,6-dimethyl-3,5-heptanediol (1), a new chiral auxiliary, has been prepared by the enantiodifferentiating hydrogenation of 2,6-dimethyl-3,5-heptanedione over tartaric acid–NaBr–modified Raney nickel catalyst (TA–NaBr–MRNi), and the preferential recrystallization of the hydrogenation product. Absolute configuration of 1 was determined to be 3S, 5S by the chemical correlation with (−)-ethyl

  • Homohelicity-enriched zinc bilinone dimers with chiral aliphatic spacers. Synthesis and application to chiral induction of a nematic liquid crystal
    作者:Shigeyuki Yagi、Katsushi Hamakubo、Shigeru Ikawa、Hiroyuki Nakazumi、Tadashi Mizutani

    The zinc bilinone (ZnBL) dimers 4 and 5 bearing chiral aliphatic spacers ((2S,4S)-2,4-pentanedioxy and (3S,5S)-2,6-dimethyl-3,5-heptanedioxy for 4 and 5, respectively) were newly prepared, and their conformational distribution was investigated. The 1H NMR and circular dichroism spectra revealed that the present dimers predominantly adopted the homohelicity conformation (MM and PP for 4 and 5, respectively)
    锌bilinone(ZnBL)二聚体4和5的轴承手性脂肪族间隔物((2小号,4小号)-2,4- pentanedioxy和(3小号,5小号)-2,6-二甲基-3,5- heptanedioxy为4和5分别)是新制备的,并对其构象分布进行了研究。的1 H NMR和圆二色性光谱显示本二聚体主要采用的构象homohelicity(MM和PP为4和5),尽管具有相应亚基结构的参考单体显示出较差的螺旋度富集。还研究了这些ZnBL二聚体对向列液晶(N-(4-甲氧基亚苄基)-4-丁基苯胺,MBBA)的螺旋扭曲能力。通过将二聚体掺入MBBA,可以实现高效的手性向列诱导。特别地,二聚物5表现出β中号的1800微米值-1。
