制备方法与用途

简介

哌啶类衍生物作为药物中间体，在医药领域具有重要的研究价值。4-哌啶乙酸甲酯也是一种重要的哌啶类衍生物药物中间体。然而，目前我国还没有真正实现工业化的制备装置，主要依赖相应的哌啶衍生物为原料，通过使用昂贵的催化剂（如氧化铂、Pd/C或Raney Ni）和苛刻的反应条件（高温高压）来合成。这种方法虽然可以得到产物，但收率较低且成本高昂，不适合大规模工业化生产。

用途

4-哌啶乙酸甲酯作为药物中间体，在医药领域主要用于合成治疗神经性疾病的药物，如抗惊厥、抗癫痫和镇静剂等。

  摘要：

  基质金属蛋白酶MMP-13在骨关节炎（OA）的软骨和骨骼的II型胶原降解中起关键作用。因此，有效的MMP-13抑制剂将是用于治疗关节炎的新型疾病改良疗法。我们的努力导致发现了一系列MMP-13羧酸抑制剂，它们不会显着抑制相关的MMP-1（胶原酶-1）或肿瘤坏死因子-α（TNF-α）转化酶（TACE）。先前已经提出（但尚未证明）抑制后两种酶可能导致副作用。鉴定出有前途的羧酸铅9并开发了收敛的合成方法。本文介绍了9的优化和化合物24f的鉴定进一步发展。化合物24f是MMP-13的亚纳摩尔抑制剂（IC 50值为0.5 nM，K i为0.19 nM），对MMP-1或TACE无活性（IC 50大于10000 nM）。此外，在MMP-13诱导的软骨降解的大鼠模型中，口服30 mg / kg（75％抑制，p <0.05）和10 mg / kg（40％抑制，p < 0.05）口服后，蛋白24f显着降低蛋白聚糖的释放。0

  Pd/C(en)-Catalyzed Chemoselective Hydrogenation with Retention of the N-Cbz Protective Group and its Scope and Limitations

  摘要：

  A chemoselective method for the hydrogenation of acetylene, olefin, azide, nitro and benzyl ester functionalities with retention of the aliphatic N-Cbz group was established. The chemoselectivity was accomplished by using a combination of 5% Pd/C-ethylenediamine [5% Pd/C(en)] and THF (or 1,4-dioxane) as a solvent, and the scope and limitations of this methodology were investigated. These results reinforce the utility of N-Cbz protective groups in synthetic chemistry, especially in peptide synthesis (C) 2000 Elsevier Science Ltd. All lights reserved.

  these molecules are assembled through the stepwise introduction of a reactivity handle in place of an aromatic C-H bond (that is, a nitro group, halogen or boronic acid) and a subsequent functionalization or cross-coupling. Here we show that aromatic amines can be constructed by direct reaction of arenes and alkyl amines using photocatalysis, without the need for pre-functionalization. The process

  用于制备芳香胺的碳-氮键的形成是全球范围内为生产高价值材料而进行的前五项反应之一，从原料化学品到药物和聚合物不等。由于这种普遍性和多样性，其制备方法影响了学术界和工业界的整个化学合成过程。通常，这些分子是通过逐步引入反应性手柄代替芳香族CH键（即硝基，卤素或硼酸）和随后的功能化或交叉偶联而组装而成的。在这里，我们表明，芳烃胺可以使用光催化作用，通过芳烃和烷基胺的直接反应来构建，而无需进行预功能化。该过程可以轻松准备高级构建基块，容忍的功能范围很广，并且可以通过批处理流协议来实现多克规模。通过对几种药物，农药，肽，手性催化剂，聚合物和有机金属配合物的修饰，证明了该策略作为后期功能化平台的优点。
