  • N.C.A. 11C-labelling of benzenoid compounds in ring positions: Synthesis of nitro-[1-11C]benzene and [1-11C]aniline
    作者:J. Steinbach、P. Mäding、F. Füchtner、B. Johannsen
    DOI:10.1002/jlcr.2580360104
    日期:1995.1
    The paper describes the first method for n.c.a 11C-ring labelling of benzenioid compounds having a reactive group for further derivatization by use of the known principle of synchronous six-electron cyclization of hexatriene systems into aromatics. Nitro-[11C]methane (1) prepared from cyclotron-produced [11C]carbon dioxide reacts in the presence of t-BuOK with 5-dimethylaminopenta-2,4-dienylidene-dimethylammonium perchlorate (2) to form 6-nitro-1-dimethylamino-[6-11C]hexatriene (3) follow by cyclization/ aromatization into nitro-[1-11C]-benzene (4) at increased temperatures. Starting from 1, nitro-[1-11C]benzene of a radiochemical purity of about 92 % and a mean specific radioactivity of 1 Ci/μmol was obtained within 7 min. Related to [11C]CO2, the reproducible radiochemical yield of 4 (decay-corrected) was 80±5 %. Reduction of 4 by heating the above reaction mixture with aqueous Na2S gave [1-11C]aniline (5) of aradiochemical purity of about 81 %. The reproducible radiochemical yield of 5 (decay-corrected) in relation to [11C]CO2 was 65±5 %, the synthesis time from 1 was 18 min.
    该论文描述了首个用于对具备进一步衍生化活性基团的苯环类化合物进行n.c.a 11C-环标记的方法,该方法利用已知的六电子环化将己三烯系统同步转化为芳香族化合物的原理。由回旋加速器产生的[11C]二氧化碳制备的硝基[11C]甲烷(1),在叔丁基钾的存在下与5-二甲氨基戊-2,4-二烯基二甲基铵高氯酸盐(2)反应,形成6-硝基-1-二甲氨基[6-11C]己三烯(3),随后在升温条件下环化/芳香化成硝基[1-11C]苯(4)。从1开始,在7分钟内获得了放射化学纯度约为92%、平均比放射性为1 Ci/μmol的硝基[1-11C]苯。相对于[11C]CO2,4的可重复放射化学产率(衰变校正)为80±5%。通过在上述反应混合物中加热与水溶液Na2S反应,将4还原,得到放射化学纯度约为81%的[1-11C]苯胺(5)。相对于[11C]CO2,5的可重复放射化学产率(衰变校正)为65±5%,从1开始的合成时间为18分钟。

    cyanine dyes and that the reductive quenching of radical intermediates is at least partially due to hydrogen abstraction from the solvent. As a consequence, a reductive cyclization of the starting materials is favored in CD2Cl2 solutions as shown for two β‐(3‐iodopropoxy)‐substituted tetronates, which underwent in dichloromethane almost exclusive reduction, but gave predominantly the cyclization products
    β-(3-碘丙氧基)-取代的α,β-不饱和内酰胺,内酯和环烯酮(八个例子)在N,N-二异丙基乙胺(Hünig碱)的二氯甲烷溶液中进行可见光照射(λ)= 419nm)。除了简单的还原反应(加氢加碘)外,在三例中还观察到了显着的环化程度。与底物的转化同时,观察到形成了颜色强烈的副产物。根据质谱证据并与已知化合物进行比较,将副产物鉴定为花青染料。它们的形成支持了以下假设:Hünig碱的二氯甲烷溶液的辐射导致自由基的形成,而自由基又可以引发自由基反应或与花菁前体结合。氘标记实验表明,一当量的二氯甲烷被掺入花青染料中,自由基中间体的还原猝灭至少部分是由于从溶剂中抽出氢。如图所示,是两个β-(3-碘丙氧基)-取代的四价酸盐的2 Cl 2溶液,它们在二氯甲烷中几乎全部还原,但主要生成CD 2 Cl 2中的环化产物。

    fused to a fully unsaturated eight‐membered ring. A theoretical calculation predicts that the 10‐position of 1 should have the highest electron density. In agreement with this prediction, the reactions of 1 with electrophiles occur predominantly at the 10‐position. The corresponding ferrocene, two fulvenes, two diazo derivatives, and a COT‐fused azulene were obtained by the reactions of 1 with appropriate
