    摘要:
    通过开发合成前体3-乙基-2-羟基-5,7,8-三甲氧基-6-甲基-1,4-萘醌的途径,已完成了对细胞毒性的比那撒林衍生物羟卡巴酮的简明正式全合成。在Rapoport条件下氧化3-乙基1,2,4,5,7,8-六甲氧基-6-甲基萘得到3-乙基-2-羟基-5,7,8-三甲氧基-6-甲基-1,碱性水解后,4-萘醌的产率中等。另外,用三溴化硼处理3-乙基-1,2,4,5,7,8-六甲氧基-6-甲基萘提供了与天然存在的萘他林硼喹酮的接触的途径。3,6-二甲基-1,2,4,5,7,8-六甲氧基萘和3-乙基-1,2,4,5,7,8-六甲氧基萘的类似氧化脱甲基作用导致合成2,5 ,7,8-四羟基-3,6-二甲基-1,4-萘醌(aureoquinone)和3-ethyl-2,5,7,8-四羟基-1,4-萘醌。还开发了一种利用3-甲基-2-丁酰基-3,5,6的分子内克莱森缩合法合成3-乙基-2-羟基-5,7,8-三甲氧基-6-甲基-1

  • An expedient and efficient synthetic route to some naturally occurring polyfunctional naphthazarins
    作者:Christina L.L Chai、John A Elix、Felicity K.E Moore
    DOI:10.1016/s0040-4039(01)01940-2
    日期:2001.12
    A concise and versatile route to functionalised naphthazarins via 1,3,4,5,6,8-hexamethoxynaphthalene is described and is illustrated with the synthesis of three natural products, aureoquinone, boryquinone and 3-ethyl-2,7-dihydroxynaphthazarin.

    A set of substituted 2-hydroxy-6(7)-methoxynaphthazarins and 7(8)-hydroxypyranonaphthazarins were synthesized. The IR spectra of 2-hydroxy-6-methoxynaphthazarins and 7-hydroxypyranonaphthazarins, on the one hand, and of 2-hydroxy-7-methoxynaphthazarins and 8-hydroxypyranonaphthazarins, on the other hand, have the characteristic nonoverlapping intervals of stretching vibration frequencies of the beta -hydroxy groups. These regularities confirm the structures of cristazarin and 6-methylcristazarin, which are metabolites of lichen Cladonia cristatella.
  • First direct observation of tautomerism of monohydroxynaphthazarins by IR-spectroscopy
    作者:Valery P. Glazunov、Alla Ya. Tchizhova、Nataly D. Pokhilo、Victor Ph. Anufriev、George B. Elyakov

    日期:2002.2
    Some substituted monohydroxylated naphthazarins (5,8-dihydroxy-1,4-naphthoquinones) were synthesized and studied by IR-spectroscopy in aprotic organic solvents at ambient temperature. Two narrow stretching mode bands in the high frequency range 3540-3410 cm(-1) due to a beta-hydroxy group were observed; it was established that this effect was caused by tautomerism. This allowed the creation of a convenient and accurate method for the measurement of a small amount of tautomer engaged in rapid exchange with the principal tautomer. Solvent and substituent effects were estimated. (C) 2002 Elsevier Science Ltd. All rights reserved.
