  通过轴向-平面非对映诱导选择性合成轴向和平面手性二茂铁

  摘要：

  具有平面手性的二茂铁已成为不对称催化中配体的重要一类支架。然而，具有多手性结构的二茂铁分子尚未得到很好的探索。在此，轴向和平面手性二茂铁均通过钯/手性降冰片烯协同催化和轴向-平面非对映诱导合成。在这项工作中，手性降冰片烯用于立体选择性地控制芳族轴向手性，并进一步选择性诱导二茂铁平面手性的 C(sp 2 )-H 活化。基于密度泛函理论计算，证实了手性降冰片烯与底物的催化模型和轴向-平面非对映诱导过程。

  A copper-catalyzed amino lactonization of unsaturated carboxylic acids has been achieved as well as the analogous intermolecular three-component amino oxygenation of olefins. The transformation features mild conditions and a remarkably broad substrate scope, offering a novel and efficient approach to construct a wide range of amino lactones as well as 1,2-amino alcohol derivatives.

• Pd-catalyzed asymmetric Suzuki–Miyaura coupling reactions for the synthesis of chiral biaryl compounds with a large steric substituent at the 2-position

  日期：——

  Pd-catalyzed asymmetric Suzuki–Miyaura couplings of 3-methyl-2-bromophenylamides, 3-methyl-2-bromo-1-nitrobenzene and 1-naphthaleneboronic acids have been successfully developed and the corresponding axially chiral biaryl compounds were obtained in very high yields (up to 99%) with good enantioselectivities (up to 88% ee) under mild conditions. The chiral-bridged biphenyl monophosphine ligands developed

  已成功开发了Pd催化的3-甲基-2-溴苯基酰胺，3-甲基-2-溴-1-硝基苯和1-萘硼酸的不对称Suzuki-Miyaura偶联，并以很高的收率获得了相应的轴向手性联芳基化合物（最高99％），在温和条件下具有良好的对映选择性（最高88％ee）。由我们小组开发的手性桥联联苯基单膦配体在反应性和对映选择性控制方面均显示出优于萘基对应MOP的优势。溴苯底物的π共轭邻位取代基的较大位阻以及羰基与钯之间的Pd··O相互作用似乎对实现高对映选择性至关重要。

  carboxyl-containing DPP-4 inhibitors were highly potent but were poorly bioavailable. Esters of the carboxyl analogs exhibited a significant DPP-4 potency loss albeit with enhanced oral absorption. Herein, we described identification and structure–activity relationship (SAR) exploration of a novel series of benzoic acid and ester derivatives as low single-digit nanomolar DPP-4 inhibitors. Importantly, the

  我们之前报道的含羧基的 DPP-4 抑制剂非常有效，但生物利用度很低。羧基类似物的酯表现出显着的 DPP-4 效力损失，尽管具有增强的口服吸收。在此，我们描述了一系列新型苯甲酸和酯衍生物作为低个位数纳摩尔 DPP-4 抑制剂的鉴定和构效关系 (SAR) 探索。重要的是，酯显示出与酸对应物相当的活性。分子模拟显示酯采用与酸相似的结合方式。此外，所选择的酯和酸表现出高选择性和低细胞毒性，以及良好的代谢稳定性。更重要的是，这些酯类具有出色的口服药代动力学特征。最好的复合酯图19b在体内证明了长时间的 DPP-4 抑制，并在正常和 db/db 小鼠中显着改善了葡萄糖耐量，同时确保了慢性治疗中的降糖效力。我们的结果支持化合物19b可作为治疗 2 型糖尿病的潜在候选药物。
