• Small Molecule Library Synthesis Using Segmented Flow

  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到硅纳米颗粒不等。本文介绍了一种利用流动化学合成化合物库的方法，该方法采用氟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。

  Abstract In a one-pot procedure, CuBr2 has been used as a efficient desulfurizing agent in the synthesis of 2-aminothiazoles by the condensation of in situ-generated 1-substituted thioureas from their dithiocarbamic acid salts, with in situ-generated α-bromoketones from ketones. All reactions were carried out under optimized reaction conditions and gave the target products in 61–95% yield.

  A highly efficient and facile method has been described for the synthesis of substituted 2-aminothiazoles in water without any added catalyst or co-organic solvent. The reaction was carried out at ambient temperature and the products were obtained in excellent isolated yields. The developed protocol is successfully applied for the preparation of an anti-inflammatory drug, fanetizole.
