  • Small Molecule Library Synthesis Using Segmented Flow
    作者:Christina M. Thompson、Jennifer L. Poole、Jeffrey L. Cross、Irini Akritopoulou-Zanze、Stevan W. Djuric

    Flow chemistry has gained considerable recognition as a simple, efficient, and safe technology for the synthesis of many types of organic and inorganic molecules ranging in scope from large complex natural products to silicon nanoparticles. In this paper we describe a method that adapts flow chemistry to the synthesis of libraries of compounds using a fluorous immiscible solvent as a spacer between reactions. The methodology was validated in the synthesis of two small heterocycle containing libraries. The reactions were performed on a 0.2 mmol scale, enabling tens of milligrams of material to be generated in a single 200 mL reaction plug. The methodology allowed library synthesis in half the time of conventional microwave synthesis while maintaining similar yields. The ability to perform multiple, potentially unrelated reactions in a single run is ideal for making small quantities of many different compounds quickly and efficiently.
    流动化学作为一种简便、高效且安全的合成技术,已获得广泛认可,适用于多种有机和无机分子的制备,其规模从复杂的大型天然产物纳米颗粒不等。本文介绍了一种利用流动化学合成化合物库的方法,该方法采用烃不溶性溶剂作为反应间的间隔物。我们在合成两个含小杂环的化合物库中验证了该方法。反应规模为0.2毫摩尔,单次200毫升反应插件即可生成数十毫克的物质。与传统微波合成相比,该方法在保持相似产率的同时,将化合物库合成时间缩短了一半。能够在单次运行中进行多个潜在不相关的反应,这为快速高效地制备少量多种不同化合物提供了理想条件。

  • Microwave-mediated pyrazole fluorinations using selectfluor<sup>®</sup>
    作者:Joseph C. Sloop、James L. Jackson、Robert D. Schmidt
    DOI:10.1002/hc.20556
    日期:——
    Microwave-mediated electrophilic fluorinations and a new single-pot condensation en route to ring-fluorinated pyrazoles were examined: The monofluorination by these methods was successful for a variety of pyrazoles, with yields ranging from 13% to 75%. While electrophilic aromatic fluorination of 3-CF3 pyrazoles proved largely ineffective, development of a single-pot process overcame this limitation
    研究了微波介导的亲电化和一种新的单锅缩合在环吡唑的过程中:通过这些方法的单化对各种吡唑是成功的,产率范围为 13% 到 75%。虽然 3-CF3 吡唑的亲电芳族化被证明在很大程度上是无效的,但单锅法的发展克服了这一限制。微波介导的反应具有区域选择性;杂环的环化优先发生在苯基和烷基取代基上。当需要时,烷基侧链化可以通过反应物比率进行调节。单锅法,包括 H-TEDA 的酸催化,生产 4-吡唑类产品。© 2009 Wiley Periodicals, Inc. 杂原子化学 20:341–345, 2009; 在线发表于 Wiley InterScience (www.interscience. wiley.com)。DOI 10.1002/hc.20556
