  Improved specific Synthesis of [1?-15N]- and [3?-15N]L-histidine

  摘要：

  AbstractSpecifically, 15N‐enriched L‐histidines have been prepared. The labelling methodology involves introduction of labels in its precursor 1‐benzyl‐5‐hydroxy methyl imidazole, which is converted into L‐histidine via the Schöllkopf method. The procedure allows the preparation of the intermediates and finally histidine with high 15N enrichment (99%) at each position, in 29% overall yield starting with 15NH4Cl and 56% with KSC15N, respectively.

• A Continuous-Flow Method for the Desulfurization of Substituted Thioimidazoles Applied to the Synthesis of Etomidate Derivatives
  作者：Marcus Baumann、Ian R. Baxendale

  日期：2017.12.1

  A simple yet robust flow set-up for the efficient desulfurization of a series of thioimidazoles is presented, which generates the corresponding imidazole derivatives in high yields. The strategic choice of peristaltic over piston pumps allowed reliable delivery of the heterogeneous stream of the thioimidazole substrate into a T-piece where it reacted with NaNO2 in the presence of acetic acid. This

  提出了一种用于一系列硫代咪唑有效脱硫的简单而稳健的流程设置，它以高产率生成相应的咪唑衍生物。蠕动泵而不是活塞泵的战略选择允许将硫代咪唑底物的异质流可靠地输送到 T 型管中，在 T 型管中它在乙酸存在下与 NaNO2 反应。这种方法能够控制和安全地形成反应性亚硝基物种，而不会像相关批次协议中观察到的那样不受控制地暴露于有害的一氧化二氮副产品。通过有效的一锅 Corey-Gilman-Ganem 氧化程序，将所得咪唑产品转化为代表已知镇痛药依托咪酯新衍生物的各种酯，进一步证明了所得咪唑产品的价值。
