  A pH Study on the Chiral Ketone Catalyzed Asymmetric Epoxidation of Hydroxyalkenes

  摘要：

  A detailed study shows that the chiral ketone catalyzed asymmetric epoxidations of hydroxyalkenes are highly pH dependent. The lower enantioselectivity obtained at low pH is attributed to the substantial contribution of the direct epoxidation by Oxone. At high pH the epoxidation mediated by chiral ketone out-competes the racemic epoxidation, leading to higher enantioselectivity. The effective substrates include allylic alcohol, homoallylic alcohol, and bishomoallylic alcohol. In most cases, over 90% ee was obtained.

  This article describes a highly effective catalytic asymmetric epoxidation method for olefins using potassium peroxomonosulfate (Oxone, Dupont) as oxidant and a fructose-derived ketone (1) as catalyst. High enantioselectivies have been obtained for trans-disubstituted and trisubstituted olefins which can bear functional groups such as tributylsilyl ether, acetal, chloride, and ester. The enantiomeric

  本文描述了一种使用过一硫酸钾（Oxone，Dupont）作为氧化剂和果糖衍生的酮 (1) 作为催化剂的烯烃高效催化不对称环氧化方法。对于可以带有三丁基甲硅烷基醚、缩醛、氯化物和酯等官能团的反式二取代和三取代烯烃，已经获得了高对映选择性。顺式烯烃和末端烯烃的对映体过量还不高。目前的环氧化反应表明，提高 pH 值后催化剂效率显着提高。机理研究表明，环氧化主要通过螺过渡态进行，这为预测反应的立体化学结果提供了模型。平面过渡态可能是主要的竞争途径。
• Unravelling the olefin cross metathesis on solid support. Factors affecting the reaction outcome

  Olefin cross metathesis on solid support under a variety of conditions is described. A comprehensive analysis considering diverse factors governing the reaction outcome gives a series of patterns for the application of this useful methodology in organic synthesis. If the intrasite reaction is not possible, homodimerization of the soluble olefin is crucial. When the homodimer is less reactive than its monomer, reaction outcome depends on the homodimerization rate, which, in turn, depends on the precatalyst used and the reaction conditions. If the site–site interaction is a feasible process, the cross metathesis product is obtained exclusively when the newly-formed double bond is resilient to further metathetic events. Taking into account these considerations, we have demonstrated that excellent results in terms of cross metathesis coupling can be obtained under the optimized conditions, and that microwave irradiation is also an interesting alternative for the development of a practical and energy-efficient cross metathesis on solid support.

  描述了在多种条件下固体支持上的烯烃交叉致密反应。对影响反应结果的各种因素进行综合分析，提供了一系列模式，便于在有机合成中应用这一有用的方法论。如果站点内反应不可行，溶解烯烃的同聚化至关重要。当同聚物的反应性低于其单体时，反应结果取决于同聚化速率，而这又取决于所使用的前催化剂和反应条件。如果站点间相互作用是可行的过程，当新形成的双键对进一步的致密反应具有抵抗力时，将独占性地获得交叉致密产物。考虑到这些因素，我们展示了在优化条件下可以获得交叉致密耦合的优秀结果，并且微波辐射也是开发实用且节能的固体支持交叉致密反应的一个有趣选择。

  We have prepared immobilized olefins as models for the cross metathesis using different olefin partners in the presence of second generation Grubbs and Hoveyda−Grubbs precatalysts. We have demonstrated that solid-phase cross metathesis is strongly dependent on the degree of homodimerization of the non-immobilized olefin and the reactivity of such a homodimer. As in the homogeneous phase, the Hoveyda−Grubbs

  在第二代Grubbs和Hoveyda-Grubbs预催化剂的存在下，我们使用不同的烯烃伙伴制备了固定化烯烃作为交叉复分解的模型。我们已经证明固相交叉复分解强烈地依赖于未固定化烯烃的均二聚化程度和这种均二聚体的反应性。与在均相中一样，Hoveyda-Grubbs预催化剂对于固定化的α，β-不饱和羰基化合物更好。

  chelate-controlled intermolecular oxidative Heck reaction is reported that proceeds with a wide range of nonresonance stabilized alpha-olefin substrates and organoboron reagents to afford internal olefin products in good yields and outstanding regio- and E: Z stereoselectivities. Pd-H isomerization, common in many Heck reactions, is not observed under these mild, oxidative conditions. This is evidenced
