    Synthesis and characterization of κ-2-bis-N-heterocyclic carbene rhodium(I) catalysts: Application in enantioselective arylboronic acid addition to cyclohex-2-enones
    摘要:
    This manuscript describes the synthesis and characterization of new derivatives of di-N-heterocyclic carbene (diNHC) ligands derived from trans-9,10-dihydro-9,10-ethanoanthracene-11,12-diylmethanediyl (DEAM) and trans-9,10-dihydro-9,10-ethanoanthracene-11,12-diyl (DEA). Synthesized as the diazolium salts, the new ligands are employed, in conjunction with known derivatives, to examine specific properties than influence the chiral induction in rhodium-catalyzed arylboronic acid addition to cyclohex-2enones. Three properties of the diNHC ligands are modified and include: 1) the size and composition of the N-heterocyclic substituent (Me, Pr-i, Bn, CHPh2, o-MeBn, and R-CHMePh), 2) the type of N-heterocycle (benzimidazole versus imidazole), and 3) the size of the chiral pocket (DEAM versus DEA). Results from the catalytic studies indicate the DEAM ligand, which contains an extra CH2 group compared to DEA, is too flexible to induce enantiomeric excess. The DEA derivatives containing an imidazole or benzimidazole provide distinctly different results despite relatively small differences between the heterocyclic carbene donors. An unexpected source of chiral induction is rationalized using results from catalytic data (% e.e.) and complemented by X-ray structural data and DFT calculations. Published by Elsevier B.V.

Moreover, the evaluation of an Ir catalyst precursor showed that cationic [Ir(cod) 2 ]BF 4 complex could be used. Furthermore, the introduction of a chiral hydroxyamide side arm into the benzimidazolium salt was critical for the successful design of

    New benzimidazolium sulfonate salts have been prepared and fully characterized. They have been associated in situ with [RuCl2(p-cymene)]2 to generate efficient catalytic systems operating at 120 °C under neat conditions in the presence of potassium tert-butylate for selective N-alkylation of primary aromatic amines into secondary amines.

    concept, we succeeded in the development of a series of highly active and selective inhibitors of CYP11B1, the key enzyme of cortisol biosynthesis, as potential drugs for the treatment of Cushing's syndrome and related diseases. Thus, compound 33 (IC50 = 152 nM) is the first CYP11B1 inhibitor showing a rather good selectivity toward the most important steroidogenic CYP enzymes aldosterone synthase (CYP11B2)
    从基于依托咪酯的设计概念出发,我们成功开发了一系列高活性和选择性抑制剂CYP11B1(皮质醇生物合成的关键酶),作为治疗库欣综合症和相关疾病的潜在药物。因此,化合物33(IC50 = 152 nM)是第一种CYP11B1抑制剂,对最重要的类固醇生成CYP酶醛固酮合酶(CYP11B2),形成雄激素的CYP17和芳香​​酶(雌激素合酶CYP19)表现出相当好的选择性。

    combination of [Pd(allyl)Cl]2 and the azolium salt 9, containing a 3-pentyl group at N(3) position in the NHC ring, efficiently promoted the AAA reaction to afford the corresponding alkylated product 7 with 67% ee. Furthermore, it was found that the Pd/NHC ratio was an important factor; the AAA reaction with a Pd/NHC ratio of 1:1 took place smoothly, whereas utilization of a Pd/NHC ratio of 1:2 resulted
    研究了阴离子束缚的NHC配体体系在Pd催化的烯丙基不对称烷基化(AAA)反应中的多功能性。定义明确的阴离子酰胺化物/ NHC-Pd(II)络合物催化1,3-二苯基丙-3-烯-1-基乙酸酯(5)与NaCH(CO 2 Me)2的AAA反应。同样,通过使用原位生成的NHC-Pd(II)配合物发生AAA反应。各种NHC配体前体的筛选显示[Pd(烯丙基)Cl] 2和重氮盐9的组合有效地促进了AAA反应,该重氮盐9在NHC环的N(3)位置含有一个3-戊基。得到相应的烷基化产物7拥有67%的ee。另外,发现Pd / NHC比是重要的因素。Pd / NHC比为1:1的AAA反应顺利进行,而Pd / NHC比为1:2的利用可能导致底物的转化率较低,这可能是由于形成了催化惰性的bis(NHC)–Pd (二)情结。事实上,一项独立的实验表明,双(NHC)-Pd(II)络合物是通过用两当量的NHC-Ag络合物处理[Pd(烯丙基)Cl]
