  Addition of Oxime Derivatives to Alkynyl Fischer Carbene Complexes

  摘要：

  The addition of oxime derivatives to alkynyl Fischer carbene complexes has been explored through a combined experimental and computational approach. Up to four different heterocycles with diverse regiochemistry and ring size were found, depending on the starting ketone. The reaction mechanism was studied by DFT methods.

  Camptothecin-based compounds are useful for treating a neoplasm in mammalian subjects by administering such compound to the subjects in combination with radiotherapy, i.e., the treatment of tumors with radioactive substances or radiation from a source external to the subject. Camptothecin-based compounds are modified by positioning at least one electron-affinic group around the camptothecin structure to enhance their value in combination with radiotherapy. New Camptothecin-based compounds are disclosed that are useful for treating cancer by administering the novel compounds alone or in combination with radiotherapy.

  基于紫杉醇的化合物通过将该化合物与放射疗法结合在一起向哺乳动物体内施用，对治疗肿瘤具有益处，即使用放射性物质或来自主体外部源的辐射治疗肿瘤。通过在紫杉醇结构周围定位至少一个电子亲和基团来改性基于紫杉醇的化合物，以增强它们与放射疗法结合的价值。还披露了新的基于紫杉醇的化合物，可通过单独或与放射疗法结合使用这些新化合物来治疗癌症。

• The Reaction of Ketoximes with Hypervalent Iodine Reagents: Beckmann Rearrangement and Hydrolysis to Ketones

  We investigated the reaction of ketoximes with hypervalent iodine reagents. A combination of PhI(OAc)2 and BF3·Et2O promoted the Beckmann rearrangement of ketoximes, thus yielding the corresponding amides. From a detailed investigation of the reaction, we determined that the Beckmann rearrangement is preceded by acetylation of the hydroxy group of the ketoxime in situ, accelerating the Beckmann rearrangement

  我们研究了酮肟与高价碘试剂的反应。PhI(OAc) 2和BF 3 ·Et 2 O的组合促进了酮肟的贝克曼重排，从而产生了相应的酰胺。通过对反应的详细研究，我们确定贝克曼重排之前是酮肟的羟基原位乙酰化，加速了贝克曼重排。我们证实乙酰化酮肟与BF 3 ·Et 2 O 发生贝克曼重排。酮肟与Koser 试剂[PhI(OH)OTs] 在四氢呋喃存在下发生水解，在室温下以高产率提供相应的酮温度。
• N-Substituted Imines by the Copper-Catalyzed <i>N</i>-Imination of Boronic Acids and Organostannanes with <i>O</i>-Acyl Ketoximes

  日期：2007.5.1

  Catalytic quantities of copper(I) or copper(II) sources catalyze the N-imination of boronic acids and organostannanes through reaction with oxime O-carboxylates under nonbasic conditions. This method tolerates various functional groups and takes place efficiently using aryl, heteroaryl, and alkenyl boronic acids and stannanes.
