    3-氰基-1-萘甲酸的制备新路线
    摘要:
    3-Cyano-1-naphthalenecarboxy acid 是制造速激肽受体拮抗剂所需的中间体。萘骨架上的 1,3-二取代模式使这种氰酸的合成复杂化。由于汞盐的化学计量使用、低产率和其他操作困难,以前基于文献的化学对大规模生产没有吸引力。通过 3-溴香豆酸盐在仅用于萘 2 环系统一半的碳原子上建立 1,3-取代,然后通过Diels-Alder 将 3-溴香豆酸盐添加到原位生成的苯中。通过将酯转化为腈,然后将溴取代基羰基化,将所得的 4-溴-2-萘甲酸酯转化为所需的氰酸。新路线已成功扩大规模,并在改进工艺方面与以前的文献化学相比具有显着优势……

    摘要:
    A facile solid-phase synthetic approach to the synthesis of 3,4-disubstituted-2-aminothiazolium derivatives was reported. Functionalized aminomethylphenyl silica gel was used as a 'volatilizable' support. The products were cleaved with 10% HF and were obtained in high yields and purities. (C) 2010 Elsevier Ltd.

  • Kinetic Resolution of Nitrogen Heterocycles with a Reusable Polymer-Supported Reagent
    作者:Imants Kreituss、Yuta Murakami、Michael Binanzer、Jeffrey W. Bode
    DOI:10.1002/anie.201204991
    日期:2012.10.15
    Shake it up baby! Simply shaking a polymer‐supported reagent and the racemic amine at room temperature kinetically resolves a broad range of N‐heterocycles with good selectivity. The polymer‐supported reagents are robust, easy to regenerate, and can be reused dozens of times. Cleavable acyl groups can be used to give access to both amine enantiomers in a single resolution.
    摇摇宝贝!只需在室温下摇晃聚合物支撑的试剂和外消旋胺,就可以动力学分离宽范围的N-杂环,并具有良好的选择性。聚合物支持的试剂坚固耐用,易于再生,可以重复使用数十次。可裂解的酰基可用于以单一分辨率获得两种胺对映体。

  • CONFORMATIONALLY CONSTRAINED, FULLY SYNTHETIC MACROCYCLIC COMPOUNDS
    申请人:Obrecht Daniel
    公开号:US20120270881A1
    公开(公告)日:2012-10-25
    Conformationally restricted, spatially defined 12-30 membered macrocyclic ring systems of formulae Ia and Ib are constituted by three distinct molecular parts: Template A, conformation Modulator B and Bridge C. These macrocycles Ia and Ib are readily manufactured by parallel synthesis or combinatorial chemistry in solution or on solid phase. They are designed to interact with a variety of specific biological target classes, examples being the agonistic or antagonistic activity on G-protein coupled receptors (GPCRs), ion channels and signal transduction pathways. In particular, these macrocycles act as antagonists of the motilin receptor, the FP receptor and the purinergic receptors P2Y 1 , as modulators of the serotonin receptor of subtype 5-HT 2B , as blockers of the voltage-gated potassium channel K v 1.3 and as inhibitors of the β-catenin-dependent “canonical” Wnt pathway. Thus they are showing great potential as medicaments for a variety of diseases.
    具有结构限制的、空间定义的12-30环的大环系统Ia和Ib由三个不同的分子部分构成:模板A、构象调节剂B和桥C。这些大环Ia和Ib可以通过并行合成或溶液中或固相上的组合化学来轻松制备。它们被设计用于与各种特定的生物靶标类相互作用,例如对G蛋白偶联受体(GPCRs)、离子通道和信号转导途径的激动或拮抗活性。特别地,这些大环作为莫蒂林受体的拮抗剂、FP受体和嘌呤受体P2Y1的调节剂、5-HT2B亚型的5-羟色胺受体的调节剂、电压门控钾通道Kv1.3的阻断剂以及β-连环蛋白依赖的“经典”Wnt途径的抑制剂。因此,它们显示出作为各种疾病药物的巨大潜力。
