  • Highly Regio- and Stereoselective Ring-Opening Reaction of γ-Alkenyl-γ-butyrolactones with Allylsilanes in the Presence of Trimethyloxonium Salt Leading to Methyl 4,8-Alkadienoates
    作者:Masatoshi Kawashima、Tamotsu Fujisawa
    DOI:10.1246/bcsj.61.4051
    日期:1988.11
    The reaction of γ-alkenyl-γ-butyrolactones with allylic trimethylsilanes in the presence of trimethyloxonium tetrafluoroborate proceeded regio- and stereoselectively with an allylic rearrangement of the substrate to afford methyl (E)-4,8-alkadienoates in high yields. On the other hand, the ring opening of 4-hexen-6-olide afforded exclusively methyl (Z)-4,8-alkadienoates in high yields. The synthetic utility of the reaction was demonstrated by the short step synthesis of β-sinensal and β-farnesene.
    γ-烯基-γ-丁内酯与烯丙基三甲基硅烷在三甲基氧鎓四氟硼酸盐存在下的反应,经过区域和立体选择性,底物发生烯丙重排,生成了高产率的甲基 (E)-4,8-烯二酸酯。另一方面,4-己烯-6-内酯的开环反应则专门生成高产率的甲基 (Z)-4,8-烯二酸酯。这一反应的合成实用性通过β-辛烯醛和β-法尼烯的短步合成得到了验证。

    作者:Mercedes Álvaro、Pilar Formentín、Hermenegildo García、Emilio Palomares、María J. Sabater
    DOI:10.1021/jo020113w
    日期:2002.7.1
    Three N-alkylpyridinium photosensitizers having chiral alkyl groups have been prepared by reacting 2,4,6-triphenylpyrylium tetrafluoroborate ion with (1R,2S)-(-)-norephedrine, (S)-(+)-2-(aminomethyl)pyrrolidine, and (R)-(-)-1-cyclohexylethylamine. Laser flash photolysis allows detection of the corresponding triplet excited states that are quenched by hydrogen atom donors and electron donors. Asymmetric
    通过使2,4,6-三苯基吡啶四氟硼酸根离子与(1R,2S)-(-)-去氧麻黄碱,(S)-(+)-2-(氨基甲基)吡咯烷反应制备了三种具有手性烷基的N-烷基吡啶鎓光敏剂和(R)-(-)-1-环己基乙胺。激光闪光光解允许检测相应的三重激发态,该激发态被氢原子供体和电子供体淬灭。使用对映体纯的1,2-二氨基环己烷作为猝灭剂,观察到手性三重态激发态的不对称猝灭。使用这些手性N-烷基吡啶鎓作为光敏剂,测量了5-甲基-4-己酸向其相应的γ-内酯的光化学环化的低对映体过量值(最高为7%)。
