  This invention relates to the new epothilone derivatives of general formula I, 1 in which substituents Y, Z R 2a , R 2b , R 3 , R 4a , R 4b , D—E, R 5 , R 6 , R 7 , R 8 and X have the meanings that are indicated in more detail in the description. The new compounds interact with tubulin by stabilizing microtubuli that are formed. They are able to influence the cell-splitting in a phase-specific manner and are suitable for treating malignant tumors, for example, ovarian, stomach, colon, adeno-, breast, lung, head and neck carcinomas, malignant melanomas, acute lymphocytic and myelocytic leukemia. In addition, they are suitable for anti-angiogenesis therapy as well as for treatment of chronic inflammatory diseases (psoriasis, arthritis). To avoid uncontrolled proliferation of cells and for better compatibility of medical implants, they can be applied or introduced into polymer materials. The compounds according to the invention can be used alone or to achieve additive or synergistic actions in combination with other principles and classes of substances that can be used in tumor therapy.

  The invention relates to novel epothilone derivatives of general formula (1), wherein R 5 represents a halogen atom or a cyano group and the other substituents have the meanings as cited in the description. The novel compounds interact with tubulin by stabilizing formed microtubules. They are capable of influencing the cell division in a phase-specific manner and are well-suited for the treatment of malignant tumors, for example, ovarian, stomach, colon, adeno, breast, lung, head and neck carcinomas, malignant melanoma, acute lymphocytic and myelocytic leukemia. In addition, they are well-suited for anti-angiogenesis therapy and for the treatment of chronic inflammable medical disorders (psoriasis, arthritis). In order to prevent uncontrolled cell growths as well as to improve the compatibility of medical implants, the inventive epothilone derivatives can be applied to or introduced into polymeric materials. The inventive compounds can be used alone or in order to obtain additive or synergistic effects, in conjunction with additional principles and substance classes that can be used in tumor therapy. 1

• Rapid and efficient protic ionic liquid-mediated pinacol rearrangements under microwave irradiation
  作者：Luke C. Henderson、Nolene Byrne

  DOI：10.1039/c0gc00916d

  日期：——

  Several protic ionic liquids were tested as potential mediators for pinacol rearrangements employing microwave irradiation. Using hydrobenzoin as a model substrate, the optimal conditions were found to be heating at 80 °C for 5 min using H2SO4:triethylamine as the ionic liquid. A key feature of this reaction was to keep the microwave power low (20 W) to avoid ionic liquid degradation. Application of these conditions to triphenylethylene glycol gave rearrangement products in high yield and purity, while phenylethylene glycol and styrene oxide gave pinacol products that underwent a cascade aldol condensation. These conditions represent an efficient means by which pinacol rearrangements can be carried out while avoiding the use of strong Brønsted acids, high temperatures and extended reaction times.

  几种质子型离子液体被测试为运用微波辐射进行片呐醇重排反应的潜在介质。使用氢氧化苯偶姻作为模型底物，发现最佳条件是采用H2SO4：三乙胺作为离子液体，在80°C下加热5分钟。该反应的关键特征是保持微波功率低（20瓦）以避免离子液体降解。将这些条件应用于三苯乙烯二醇，得到了高产率和高纯度的重排产物，而苯乙烯二醇和苯乙烯氧化物则得到了进行级联醛醇缩合的片呐醇产物。这些条件提供了一种高效手段，可以在避免使用强布朗斯台德酸、高温和长时间反应的同时进行片呐醇重排反应。

  Acylation of alcohols, thiols, and sugars were studied with a variety of Lewis acids, and it was found that Cu- and Sn(OTf)2 are very efficient in catalyzing the reaction under mild conditions. Among these two catalysts, Cu(OTf)2 was preferred because of its lower cost and relatively higher yield of the acylated product. The reaction was studied in several solvents, but CH2Cl2 was preferred. It was

  研究了多种路易斯酸对醇，硫醇和糖的酰化作用，发现Cu-和Sn（OTf）2在温和条件下催化反应非常有效。在这两种催化剂中，Cu（OTf）2是优选的，因为其成本较低并且酰化产物的产率相对较高。在几种溶剂中研究了该反应，但是优选CH 2 Cl 2。还观察到，本方法适用于叔醇的酰化。糖也被酰化，在端基异构中心没有任何差向异构。在此进一步表明，该方法还适用于伯醇或仲醇相对于叔醇的选择性酰化。
