  Novel 5-substituted 1-pyrazolol analogues of ibotenic acid: Synthesis and pharmacology at glutamate receptors

  摘要：

  5-Substituted 1-pyrazolol analogues of ibotenic acid have been synthesized and pharmacologically characterized on ionotropic and metabotropic glutamate receptors (iGluRs and mGluRs). The syntheses involved introduction of bromide, alkyls, phenyl and arylalkyls in the 5-position of 1-benzyloxypyrazole leading to 5-substituted (RS)-2-amino-(1-hydroxy-4-pyrazolyl)acetic acids (5a-1). The pharmacological activities of the synthesized analogues ranged from the 5-cyclopropylmethyl analogue (5f) with weak but selective affinity for NMDA receptors (IC50 = 35 mu M), over the 5-n-propyl analogue (5c), which was a selective mGluR2 agonist (EC50 = 72 mu M), to the 5-cyclohexylmethyl analogue (5g), which was a selective mGluR2 antagonist (K-i = 32 mu M), and the 5-phenylethyl analogue (5j), which was a weak but apparently selective mGluR1 antagonist (K-i = 230 mu M). This series of compounds afforded GluR ligands with a broad spectrum of pharmacological profiles, and showing potential for development of new compounds with subtype-selective activities at various GluRs.

  and TBAB as the mild bromination reagents enables rapid transformation of a wide range of alcohols to their bromide counterparts within one to 5 min in CH3CN and DMF, which is compatible with the Ni-catalyzed cross-electrophile coupling conditions in the presence of a chemical reductant. The present method is suitable for arylation of a myriad of structurally complex alcohols with no need for prepreparation

  未活化醇的直接偶联仍然是当前合成化学中的一个挑战。我们在此展示了一种建立在醇与芳基卤化物的原位卤化/还原偶联以形成 Csp 2 -Csp 3键的策略。2-氯-3-乙基苯并[ d ]恶唑-3-鎓盐 (CEBO) 和 TBAB 作为温和溴化试剂的组合能够在 CH 3 中在一到 5 分钟内将范围广泛的醇快速转化为其溴化物对应物CN 和 DMF，在化学还原剂存在下与 Ni 催化的交叉亲电偶联条件相容。本方法适用于无数结构复杂的醇的芳基化，而无需制备卤代烷。更重要的是，温和且动力学快速的溴化过程在对称二醇的溴化/芳基化和多元醇中较少的空间位阻羟基中显示出良好的选择性，从而为二醇和多元醇的选择性官能化提供了希望，而无需费力的保护/脱保护操作。这项工作的实用性在许多碳水化合物、药物化合物和天然醇的芳基化中也很明显。

  A range of N-alkoxycarbonyl- and N-carboxamido-oxaziridines has been prepared to test the effects of oxaziridine structure on yields of enolate amination product. Side-products arising from reaction of aldehyde-derived oxaziridines with base were identified, while a ketone-derived oxaziridine afforded moderate yields of amination product with stabilised carbanions.

• Synthesis of Polysubstituted Indoles and Indolines by Means of Zirconocene-Stabilized Benzyne Complexes
  作者：Jeffrey H. Tidwell、Stephen L. Buchwald

  DOI：10.1021/ja00105a021

  日期：1994.12

  The development of a new method for the regiospecific synthesis of polysubstituted indoles and indolines is reported. The key steps involve the generation of zirconocene-stabilized benzyne complexes and subsequent intramolecular olefin insertion reactions to provide tricyclic indoline zirconacycles. The zirconacyclic intermediates were cleaved with iodine to yield diiodo indolines, which were converted to a wide variety of indole and indoline products, such as analogs of tryptamine, serotonin, tryptophan, and the pharmacophore of CC-1065.
