FVT of 22T/22A also affords 2-pyridylnitrene 19 and diazacycloheptatetraene 21, as well as glutacononitriles 27Z,E and 2- and 3-cyanopyrroles 28 and 29. Photolysis of 21 above 300 nm yields the novel spiroazirene 25, identified by its matrix IR spectrum. The reaction pathways connecting the four

  • The Preparation of the Last Remaining Acyclic Isomers of Benzene
    作者:Helmut Maurer、Henning Hopf
    DOI:10.1002/ejoc.200400869
    日期:2005.7
    The three acyclic isomers of benzene – 2,3-hexadien-5-yne, 3-methyl-1,2-pentadien-4-yne, and 1,2,3,4-hexatetraene – have been prepared by simple routes from readily available starting materials. The hydrocarbons as well as several side products formed during their synthesis were characterized by their spectroscopic data and typical cycloaddition and isomerization reactions.

    Abstract Irradiation of diazocyclopentadiene ( 1 ) in a matrix at 10 K with the wavelength λ =366 nm leads—as already known—to rapid loss of nitrogen and the formation of cyclopentadienylidene ( T-2 ). Upon photoexcitation of cyclopentadienylidene ( 2 ) with light of the wavelength λ =313 nm the ( s - E )-( E )-conformer of 2-penten-4-yn-1-ylidene ( T-7a ) can be detected, which is effectively converted
    摘要 众所周知,在 10 K 下用波长 λ = 366 nm 对基质中的重氮环戊二烯 ( 1 ) 进行辐照会导致氮的快速损失和环戊二烯 (T-2) 的形成。用波长 λ =313 nm 的光对环戊二烯基 ( 2 ) 进行光激发后,可以检测到 2-penten-4-yn-1-ylidene ( T-7a ) 的 ( s - E )-( E )-conformer,即通过使用波长为 λ = 436 nm 的光,可有效地将其转化为 3-乙炔基环丙烯 (6)。T-7a 和 6 的结构解析基于实验和计算红外光谱的比较。环戊二烯基 (2) 与同一基质笼中的消除氮一起被隔离,用波长大于 570 nm 的光照射引发对起始材料的部分逆反应,
  • Purification process

    公开(公告)日:2005-09-08
    Process for the preparation of pure allylamine pharmaceutical terbinafine of formula I in free base form or acid addition salt form, by distilling crude terbinafine base, preferably by short path distillation, e.g. at a temperature above 100° C. and reduced pressure, e.g. 0.2 mbar, and recovering the purified product in free base or acid addition salt form. The process is indicated for use in removal of metal or non-metal contaminants, optionally together with salt formation under simultaneous precipitation of pure trans isomer. Detection of non-metal contaminants such as substance A of formula preferably is effected by RP HPLC analysis with UV detection.
    制备纯烯丙胺药物特比那芬(化学式I)的过程,可以得到其自由碱基形式或酸盐加成物形式,方法是通过蒸馏粗特比那芬碱基,最好是通过短程蒸馏,例如在温度高于100℃和减压下(例如0.2毫巴)进行,然后以自由碱基或酸盐加成物形式回收纯净产品。该过程适用于去除金属或非金属污染物,可选地与盐形成同时沉淀纯的顺式异构体。检测非金属污染物,例如化合物A的公式,最好是通过RP HPLC分析与紫外线检测进行。
