  旋光氧化膦。8 1：非对称1,2-二膦基乙烯的合成及相关体系

  摘要：

  非对称和旋光反式的合成已经完成了-1，2-二膦基乙烯。所采用的加成-消除途径可能是通用的，并且利用了容易获得的仲膦氧化物和叔1-卤代戊基膦氧化物氧化物。立体拥挤的仲氧化膦通过与相应的1-溴乙烯基氧化膦在吡啶中加热直接直接提供不对称的1,2-二膦亚基乙烯。对于其他仲膦氧化物，涉及相应的1-氯乙烯基膦氧化物的两步法是更有利的。在导致光学活性1的合成中 具有等价或非等价手性磷中心的2-二膦基乙烯中心已利用新型的同型手性（-）-（1-溴乙烯基）甲基苯基膦氧化物和（-）-（1-氯乙烯基）甲基苯基膦氧化物提供了非常实用的自拆分系统一个手性磷中心分解另一个。所开发的方法也已用于合成含有一个磷和一个硫活化基团的类似的双活化乙烯。

  Vinylphosphane oxides 6 undergo catalytic olefin homo-metathesis leading to achiral and P-stereogenic diphosphane dioxides 7 with exclusive (E)-selectivity. Similarly, EWG-substituted vinylphosphane oxides 11, 12 could be prepared with complete (E)-olefin selectivity via olefin cross-metathesis with electron-deficient substrates, such as methyl acrylate and 2-fluorostyrene, using nitro-Hoveyda ruthenium

• Nitro-Substituted Hoveyda−Grubbs Ruthenium Carbenes:  Enhancement of Catalyst Activity through Electronic Activation

  The design, synthesis, stability, and catalytic activity of nitro-substituted Hoveyda-Grubbs metathesis catalysts are described. The highly active and stable meta- and para-substituted complexes are attractive from a practical point of view. These catalysts operate in very mild conditions and can be successfully applied in various types of metathesis [ring-closing metathesis, cross-metathesis (CM), and enyne metathesis]. Although the presence of a NO2 group leads to catalysts that are dramatically more active than both the second-generation Grubbs's catalyst and the phosphine-free Hoveyda's carbene, enhancement of reactivity is somewhat lower than that observed for a sterically activated Hoveyda-Grubbs catalyst. Attempts to combine two modes of activation, steric and electronic, result in severely decreasing a catalyst's stability. The present findings illustrate that different Ru catalysts turned out to be optimal for different applications. Whereas phosphine-free carbenes are catalysts of choice for CM of various electron-deficient substrates, they exhibit lower reactivity in the formation of tetrasubstituted double bonds. This demonstrates that no single catalyst outperforms all others in all possible applications.
• Synthesis of Substituted <i>P</i>-Stereogenic Vinylphosphine Oxides by Olefin Cross-Metathesis

  [GRAPHICS]Substituted vinylphosphine oxides have been prepared in good yield and exclusive (E)-olefin selectivity via olefin cross-metathesis using Grubbs and Hoveyda-type ruthenium catalysts. In addition, metathesis of chiral vinylphosphine oxides proceeds without racemization of the phosphorus chirality center, providing easy access to functionalized chiral nonracemic (E)-alkenylphosphine oxides.
