  基于M7和Ru-苄叉基-恶嗪酮设计的立体定向钌催化剂的合成与应用

  摘要：

  在M7和Ru-亚苄基-恶嗪酮设计的基础上，合成了一系列带有二硫代邻苯二酚配体的新型立体保持性钌催化剂。使用Z-和E-构型的起始原料，在开环交叉复分解反应，闭环复分解反应，交叉复分解反应和自复分解反应中测试了催化剂的活性。获得所需的复分解产物，具有中等至高产率，并具有优异的立体选择性（> 95％）。通过对内烯烃和末端烯烃进行动力学研究，发现了与底物有关的反应性。

• Synthesis of N-heterocycles, beta-amino acids, and allyl amines via aza-payne mediated reaction of ylides and hydroxy aziridines

  An ylide-based aza-Payne rearrangement of 2,3-aziridin- 1 -ols leads to an efficient process for the preparation of pyrrolidines. The aza-Payne rearrangement under the basic reaction conditions favors the formation of epoxy amines. Subsequent nucleophilic attack of the epoxide by the ylide yields a bis-anion, which upon a 5-exo-tet ring closure yields the desired pyrrolidine, thus completing the relay of the 3-membered the 5-membered nitrogen containing ring system. This process takes place with complete transfer of stereochemical fidelity, and can be applied to sterically hindered aziridinols.

  基于叶立德的2,3-氮杂环丙醇的aza-Payne重排反应导致了一种高效的吡咯烷制备过程。在碱性反应条件下进行的aza-Payne重排有利于环氧胺的形成。叶立德对环氧化物的亲核攻击产生双阴离子，随后通过5-内攻环闭合产生所需的吡咯烷，从而完成了含3-成员和5-成员氮环的环的传递。这个过程完全保持立体化学的保真度，并可应用于立体位阻的氮杂环丙醇。

  high-value compounds by cross-metathesis. The ruthenium complex is prepared from a commercially available precursor and an easily generated air-stable zinc catechothiolate. Transformations typically proceed with 5.0 mole per cent of the complex and an inexpensive reaction partner in 4–8 hours under ambient conditions; products are obtained in up to 80 per cent yield and 98:2 Z:E diastereoselectivity.

  烯烃复分解催化剂为生命科学领域的医生和研究人员提供了必不可少的分子。然而，一个持续存在的问题是缺乏直接生成无环 Z 烯丙醇的化学转化，包括含有受阻相邻取代基或反应性功能单元（如苯酚、醛或羧酸）的产品。在这里，我们提出了一种电子改性的二硫化钌催化剂，它可以通过交叉复分解有效地产生这种高价值的化合物。钌配合物由市售前体和易于生成的空气稳定儿茶酚硫醇锌制备。在环境条件下，转化通常在 4-8 小时内以 5.0 摩尔百分比的配合物和廉价的反应伙伴进行；以高达 80% 的产率和 98:2 Z:E 非对映选择性获得产品。该催化剂的使用已在天然抗肿瘤剂 Neopeltolide 的合成以及可再生原料（油酸）向抗真菌剂的一步立体选择性克级转化中得到证明。在这种转化中，新催化剂比常用的二氯钌配合物更有效地促进交叉复分解，表明其效用可能超出 Z 选择性过程。
