制备方法与用途

3-氯-4-氰基吡啶是一种用于实验室有机合成的吡啶类杂环化合物。其制备过程如下：

在-30℃并通氮气条件下，将2,2,6,6-四甲基哌啶（2.85g，20.2mmol）溶解于THF（40mL）中搅拌均匀。随后加入2.5M n-BuLi（7.7mL）。待溶液温度降至0℃后，在搅拌下保持15分钟，然后冷却至-80℃。在15分钟内，将异烟腈（1g，9.6mmol）溶解于THF（10mL）中并缓慢加入上述混合物中；接着在-80℃条件下搅拌30分钟后，在15分钟内滴加C2Cl6（4.73g，20.2mmol）的THF（10mL）溶液，并继续搅拌30分钟。随后将反应液慢慢升温至室温。

使用40mL饱和NH4Cl溶液淬灭反应后，用EtOAc萃取混合物，再用盐水洗涤并用Na2SO4干燥。过滤、浓缩残余物并在硅胶上纯化（己烷/EtOAc，4:1），得到3-氯-4-氰基吡啶。产物为淡黄色针状物，产率为937mg，收率71%；熔点为79-80°C。通过1H NMR（400 MHz, CDCl3）分析其结构，峰位分别为δ8.82 (s, 1H)，8.68 (d, J=4.92 Hz, 1H) 和 7.56 (d, J=4.84 Hz, 1H)。

  Aryl tetrahydropyridine inhibitors of farnesyltransferase: glycine, phenylalanine and histidine derivatives

  摘要：

  Inhibitors of farnesyltransferase are effective against a variety of tumors in mouse models of cancer. Clinical trials to evaluate these agents in humans are ongoing. In our effort to develop new farnesyltransferase inhibitors, we have discovered a series of aryl tetrahydropyridines that incorporate substituted glycine, phenylalanine and histidine residues. The design, synthesis, SAR and biological properties of these compounds will be discussed. (C) 2003 Elsevier Science Ltd. All rights reserved.

  17-Cyclopropylmethyl-3,14β-dihydroxy-4,5α-epoxy-6β-[(4'-pyridyl)carboxamido]morphinan 衍生物作为外周选择性μ阿片受体药物的设计、合成和生物学评价

  摘要：

  外周选择性μ阿片受体（MOR）拮抗剂可以减轻阿片类药物引起的便秘（OIC）的症状，而不会影响阿片类药物的镇痛作用。然而，与它们相关的各种不利影响，部分是由于它们相对较低的 MOR 选择性。NAP 是一种6β- N -4'-吡啶基取代的纳曲胺衍生物，以前被鉴定为主要作用于外周神经系统的有效且高度选择性的 MOR 拮抗剂。与之相关的明显腹泻促使设计和合成其类似物以研究其结构-活性关系。其中，化合物8与原始铅相比，显示出改善的药理学特征，主要作用于外周，同时增加吗啡颗粒小鼠的肠蠕动（ED 50 = 0.03 mg/kg）。与原始铅相比，ED 50的轻微下降被未观察到的不利影响很好地补偿了。因此，该化合物似乎是开发针对 OIC 的新型治疗剂的更有希望的线索。

  日期：2021.8.11

  Lewis basic salts promote benzyltrimethylsilane coupling with (hetero)aryl nitriles, sulfones, and chlorides as a new route to 1,1-diarylalkanes. This method combines the substrate modularity and selectivity characteristic of cross-coupling with the practicality of a base-promoted protocol. In addition, a Lewis base strategy enables a complementary scope to existing methods, employs stable and easily
