  通过亚稳亚胺组件的原位捕获获得酰胺连接的有机笼：溶液相双胺识别

  摘要：

  大多数形状持久的自组装有机笼是通过沉淀获得的，并在固态下进行研究。在此，我们表明亚稳态亚胺笼（不适合沉淀）可以通过原位 Pinnick 氧化条件直接捕获，产生可溶性、坚固的酰胺笼。与旁路亚胺笼不同，由此产生的笼能够耐受水解条件以暴露内部羧酸，这些羧酸会与胺（不适合亚胺笼的客体）发生 2 点结合。

  New calix-salen cobalt (III) complexes were synthesized as a mixture and as pure trimer or tetramer complexes. These cyclic complexes were used as catalysts to promote the dynamic hydrolytic kinetic resolution (HKR) of epibromohydrin in order to evaluate the effect of the cyclic structures size on the cooperative bimetallic interactions. Since the obtained catalysts were easily recovered from the reaction

  合成了新的杯-salen-钴（III）配合物，既有混合物，也有纯三聚体或四聚体。这些环状配合物被用作催化剂，以促进表溴醇的动态水解动力学拆分（HKR），以评估环状结构尺寸对协同双金属相互作用的影响。由于通过简单的过滤容易地从反应混合物中回收所获得的催化剂，因此在再循环程序中评估了它们的效率。发现环状低聚物复合物（三聚体和四聚体）和杯-salen复合物的混合物均以高对映选择性和产率递送了预期的二醇。Tetramer calix-salen钴配合物被证明是该系列中活性最高，选择性最高的催化剂。在这种情况下，

  Polycondensation reactions between various modified disalicylaldehyde derivatives and two chiral diamines afforded in each case macrocyclic structures, named calix-salen. Mixtures of oligomers (dimers to pentamers) were qualitatively analyzed by Maldi-Tof and H-1 NMR DOSY experiments allowed their easy quantitative investigation. Tuning the reaction conditions and namely the concentration of both monomeric partners led interestingly to the selective preparation of the dimer or the tetramer as main products, in diluted or concentrated media, respectively.

• Recoverable salen-based macrocyclic chiral complexes; catalysts for enantioselective Henry reactions

  Cobalt and chromium complexes have been prepared from chiral calix salen cyclic ligands. The corresponding tetrahydrosalen reduced forms have been used for copper salt complexation. These new chiral catalysts have been tested for their ability to promote asymmetric Henry reactions between various aldehydes and nitromethane under heterogeneous conditions. The best results were obtained by using tetrahydrosalen-based copper macrocycles, in terms of activity, selectivity, and stability during the recycling process. Ten consecutive runs could indeed be performed with the same catalyst batch to produce the target 1-(2-methoxy-phenyl)-2-nitro-ethanol with highly stable values in terms of yield and enantioselectivity (up to 94% ee).

  Homochiral oligomeric salen macrocycles possessing aromatic spacers have been prepared as new calix-salen derivatives. The corresponding cobalt and manganese complexes were synthesized and characterized, and their catalytic activities have been studied in the challenging hydrolysis of meso epoxides. While manganese calix-salen complexes were not active in the studied reactions, the dual heterobimetallic system, using an equimolar combination of cobalt and manganese calix-salen derivatives proved to be more enantioselective than the sole cobalt system. Furthermore, as heterogeneous complexes, the catalytic mixture could be easily recovered by simple filtration and successfully reengaged in subsequent catalytic runs. Interestingly, no need for cobalt reactivation was noticed to maintain maximum efficiency of this dual system. The matched Co/Mn dual catalyst was also used to promote the dynamic hydrolytic kinetic resolution of epibromohydrin. (C) 2016 Elsevier Ltd. All rights reserved.
