  摘要：

  三种空间定向间苯二酚[4]芳烃cavitand糖共轭物（RCGs）系列已被用作高效可回收和可重复使用的反相转移催化剂，用于生态和环境友好的硫氰化和2-氨基-1,3-噻唑在水中的形成反应。结果表明，在不使用任何共有机溶剂的情况下，RCG（1摩尔％）能够在水中容纳和催化各种水不溶性溴/硫氰酸根基质。在使用DCM或乙酸乙酯对所需产物进行简单萃取后，再对回收的含有HCG催化剂的水溶液进行处理，还检查了RCG催化体系RCG1和RCG3的可回收性和可重复使用性。RCG催化剂进入下一个反应周期。

  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。

  Treatment of 5-arylidene derivatives of 2-phenylimino-4-thiazolidinones with Grignard reagents does not open the hetero-ring, the double bond of the lateral chain, the CC bond and the CN bond of Ic, enter into reaction, yielding colourless products, believed to have structure III. On the other hand, 5-benzylidene-3-phenyl-2-phenylimino-4-thiazolidinone (Id) on treatment with Ph Mg Br undergoes addition

  copper-catalyzed coupling of oxime acetates with isothiocyanates. Various 4-substituted and 4,5-disubstituted 2-aminothiazoles were formed smoothly under mild reaction conditions. This process involved copper-catalyzed N–O bond cleavage, activation of vinyl sp2 C–H bonds, and C–S/C–N bond formations. It is noteworthy that the oxime acetates were used not only as a substrate but also as a single oxidant

  通过肟肟铜与异硫氰酸酯的铜催化偶联，开发了2-氨基噻唑的新策略。在温和的反应条件下平稳地形成了各种4-取代的和4,5-二取代的2-氨基噻唑。该过程涉及铜催化的N–O键断裂，乙烯基sp 2 C–H键的活化以及C–S / C–N键的形成。值得注意的是，肟肟不仅用作底物，而且用作单一氧化剂。

  The heterogeneous coupling reaction of oxime acetates with isothiocyanates was achieved at 110 °C in toluene in air in the presence of a bidentate nitrogen-functionalised MCM-41-immobilised copper(I) complex (MCM-41-2N-CuI) with Cs2CO3 as base to afford a variety of 2-aminothiazoles in good yields. The MCM-41-2N-CuI catalyst can be easily recovered by a simple filtration and reused at least eight times

  An efficient and expeditious catalyst-free protocol was developed for the construction of di- and trisubstituted thiazoles from -haloketones and thioureas/thioamides in PEG. The reaction was carried out at ambient temperature, and the products were obtained in excellent isolated yields (91-98%). Additionally, PEG could be recovered easily and was reused without evident loss in activity.
