  • Reaction of Pyrylium Salts with Nucleophiles. 23: Triarylethene Derivatives Containing an Oxyalkyleneamino or Oxyalkylene-N-pyridinium Side Chain
    作者:Octavian Stanciuc、Alexandru T. Balaban
    DOI:10.1002/jps.2600820911
    日期:1993.9
    amines related to anticancer drugs clomiphene and tamoxifen on the basis of key intermediates with a phenolic group, to which a side chain (omega-aminoethoxy or omega-aminopropoxy) was attached. These compounds were then reacted with 2,4,6-trimethyl- or 2,4,6-triphenylpyrylium salts. This afforded pyridinium analogues of clomiphene and tamoxifen as potential therapeutic agents for treatment against hormone-dependent
    设计了一种合成设计,用于制备与抗癌药克罗米芬和他莫昔芬有关的伯胺,该伯胺的主要中间体是带有酚基的中间体,该中间体上连接有侧链(ω-氨基乙氧基或ω-氨基丙氧基)。然后使这些化合物与2,4,6-三甲基-或2,4,6-三苯基吡啶鎓盐反应。这提供了克罗米芬和他莫昔芬的吡啶鎓类似物作为针对激素依赖性肿瘤的潜在治疗剂。

    Reduction of nitro substituted 2,5-diaryloxazoles with hydrazine hydrate and Raney nickel affords in good yield 2,5-diaryloxazoles having amino group(s) on the aryl ring(s) . The reaction of 2,4,6-trisubstituted pyrylium perchlorates with mono- and diamino-2,5-diaryloxazoles yields new mono- and bispyridinium perchlorates with a central 2,5-diaryloxazole group. Their electronic, 13C NMR and 1H NMR spectra are presented and discussed.

    用水合肼和Raney镍还原硝基取代的2,5-二芳基噁唑醇,可以得到含有氨基的2,5-二芳基噁唑醇,收率较高。2,4,6-三取代吡啶盐酸盐与单氨基和二氨基-2,5-二芳基噁唑醇的反应产生新的中央含有2,5-二芳基噁唑醇基团的单和双吡啶盐酸盐。它们的电子、13C NMR和1H NMR光谱已经被提出并讨论。
  • The 1,2,4-Triazolyl Cation:  Thermolytic and Photolytic Studies
    作者:Rudolph A. Abramovitch、Joseph M. Beckert、Harry H. Gibson,、Anthony Belcher、Greg Hundt、Tommy Sierra、Santiago Olivella、William T. Pennington、Albert Solé

    The generation of the 1,2,4-triazolyl cation (1) has been attempted by the thermolysis and photolysis of 1-(1,2,4-triazol-4-yl)-2,4,6-trimethylpyridinium tetrafluoroborate (2) and the thermolysis of 1- and 4-diazonium-1,2,4-triazoles, using mainly mesitylene as the trapping agent. Thermolysis of 2 gave mostly 1,2,4-triazole, together with 3-(1,2,4-triazol-4-yl)-2,4,6-trimethylpyridine, 4-(1,2,4-triazol-4-ylmethyl)-2
    1,2,4-三唑基阳离子(1)的产生已通过1-(1,2,4-triazol-4-yl)-2,4,6-三甲基吡啶四氟硼酸(2 )和1-和4-重氮-1,2,4-三唑的热解,主要使用均三甲苯作为捕集剂。2的热解主要产生1,2,4-三唑以及3-(1,2,4-三唑-4-基)-2,4,6-三甲基吡啶,4-(1,2,4-三唑- 4-基甲基)-2,6-二甲基吡啶和4-(2,4,6-三甲基苄基)-2,6-二甲基吡啶。在均三甲苯存在下,每种重氮盐的热分解再次主要得到三唑以及极低产率的1-(1,2,4-三唑-1-基)-2,4,6-三甲基苯和相应的-4 -基异构体的比例大致相同。另一方面,2在均三甲苯中的光解主要产生1-(1,2,4-三唑-1-基)-2,4,6-三甲基苯。已经观察到光致电子从均三甲苯转移至2,并且已经进行了2和相应的2,4,6-三苯基吡啶鎓盐的初步激光闪光光解。观察到的瞬变被解释为是由吡啶盐的第一
  • Reduction of pyrylium salts with sodium borohydride
    作者:A.T. Balaban、G. Mihai、C.D. Nenitzescu
    DOI:10.1016/s0040-4020(01)92659-6
    日期:1962.1
    Sodium borohydride converts 2,4,6-trialkylpyrylium salts (I) into a mixture of dienones (III) and lower-boiling products, which are probably 4H-pyrans (IV). The latter products yield derivatives of 1,5-diones in acid medium, and are believed to be formed by addition of the hydride ion to the γ-position of the pyrylium salt, while the former dienones arise by addition to the α-position.
    硼氢化钠将2,4,6-三烷基吡啶鎓盐(I)转化为二烯酮(III)和低沸点产物的混合物,它们可能是4H-吡喃(IV)。后者的产物在酸性介质中产生1,5-二酮的衍生物,并且据信是通过将氢化物离子加到吡喃鎓盐的γ-位上而形成的,而前者的二烯酮是通过将α-位加成而形成的。
  • Δ3-Dihydropyrans and tetrahydropyrans by reduction of pyrylium salts with sodium borohydride in acetic acid
    作者:Teodor-Silviu Balaban、Alexandru T Balaban
    DOI:10.1016/s0040-4039(00)95365-6
    日期:1987.1
    major reduction products with triacetoxyborohydride (NaBH4 in AcOH) of 2,4,6-trisubstituted pyrylium salts bearing alkyl substituents in the 2- and/or 6- position are the Δ3-dihydropyrans with 2- and 6- substituents and the all--2,4,6-trisubstituted tetrahydropyrans. Δ3-Dihydropyrans are shown to be formed 2H-pyrans by a 1,4 reduction while tetrahydropyrans result from 4H-pyrans by reduction of both
    主要还原产物与三乙酰氧基硼(加入NaBH 4的AcOH)2,4,6-三取代的吡喃鎓盐轴承烷基取代基在2-和/或6-位置是Δ 3 -dihydropyrans与2-和6-取代基和全-2,4,6-三取代的四氢吡喃。Δ 3 -Dihydropyrans被示出为形成由1,4-还原2H吡喃而四氢吡喃通过还原既烯醇-醚双键的从4H-吡喃导致。
