  3-Phenyl-Substituted Imidazo[1,5-a]quinoxalin-4-ones and Imidazo[1,5-a]quinoxaline Ureas That Have High Affinity at the GABA_A/Benzodiazepine Receptor Complex

  摘要：

  A series of imidazo[1,5-alpha]quinoxalin-4-ones and imidazo[1,5-alpha]quinoxaline ureas containing substituted phenyl groups at the 3-position was developed. Compounds within the imidazo-[1,5-alpha]quinoxaline urea series had high affinity for the GABA(A)/benzodiazepine receptor complex with varying in vitro efficacy, although most analogs were partial agonists as indicated by [S-35]TBPS and Cl- current ratios. Interestingly, a subseries of piperazine ureas was identified which had biphasic efficacy, becoming more antagonistic with increasing concentration. Analogs within the imidazo [1,5-alpha] quinoxalin-4-one series had substantially decreased binding affinity as compared to the quinoxaline urea series. These compounds ranged from antagonists to full agonists by in. vitro analysis, with several derivatives having roughly 4-fold greater intrinsic activity than diazepam as indicated by Cl- current measurement. Numerous compounds from both series were effective in antagonizing metrazole-induced seizures, consistent with anti-convulsant properties and possible anxiolytic activity. Most of the quinoxaline ureas and quinoxalin-4-ones were active in an acute electroshock physical dependence side effect assay in mice precluding further development.

  Mix and match: Similar to a galaxy consisting of millions of stars, a multicomponent reaction (MCR) system can result in millions of compounds. The MCR of α‐amino acids, oxo components, isocyanides, and amines leads to numerous and diverse compounds, thus having enormous potential for drug discovery or catalyst screening.

  novel reaction produces α-tetrazolyl N-heterocycles directly from N-heterocycles without involving pre-functionalization/pre-oxidation steps. Importantly, the stereoselective reaction involving chiral amines or chiral isocyanides allowed the expeditious syntheses of nucleoside analogs and α-tetrazolyl pyrrolidine in enantioenriched form.

  据报道，前所未有的立体选择性C（sp 3）-H功能化使Ugi-叠氮化物（CH-Ugi-叠氮化物）反应成为可能。该新颖的反应直接从N-杂环产生α-四唑基N-杂环，而无需涉及预功能化/预氧化步骤。重要的是，涉及手性胺或手性异氰化物的立体选择性反应允许对映体富集形式的核苷类似物和α-四唑基吡咯烷的快速合成。

  concise synthesis of chirally pure quinapril hydrochloride is described. The key step is the formation of α-amino amide backbone in one step using Ugi three component reaction. This method allows short access to α-amino amide chain which is a part of many drugs used for treatment of high blood pressure. A large molecular library can be synthesized by changing the components in Ugi reaction. GRAPHICAL

  5‐Triazinanes were used as easily accessible, bench‐stable formaldimine surrogates in the Ugi reaction for rapid assembly of glycinamide derivatives with three elements of diversity, in good to nearly quantitative yields. This protocol was applied for one‐pot two‐step syntheses of lidocaine and several unsymmetrically substituted diketopiperazines.

  advantages of our methodology include an increased synthesis speed, very mild conditions giving access to hitherto unknown or highly reactive classes of isocyanides, rapid access to large numbers of functionalized isocyanides, increased yields, high purity, proven scalability over 5 orders of magnitude, increased safety and less reaction waste resulting in a highly reduced environmental footprint. For example

  异氰酸酯官能团由于其在类胡萝卜素和三键特征之间的二分法而具有亲核和亲电子末端碳，在有机化学中表现出不同寻常的反应性，例如在Ugi反应中。不幸的是，仅按比例使用几种异氰酸酯妨碍了有关该官能团引人入胜的反应性的新发现。具有多个官能团的多种异氰酸酯的合成漫长，效率低下，并使化学家暴露于危险的烟雾中。在这里，我们提出了一种创新的异氰酸酯合成方法，它通过避免在96孔微量滴定板中以0.2 mmol规模在0.5 mol克规模进行平行合成而避免的水后处理，克服了这些问题。我们方法的优势包括提高合成速度，在非常温和的条件下可以使用迄今为止从未有过的未知或高度反应性的异氰酸酯类，可以快速使用大量官能化的异氰酸酯，具有较高的收率，高纯度，经过验证的5个数量级以上的可扩展性，增加的安全性和较少的反应浪费，从而大大减少了环境脚印。例如，迄今为止认为是不稳定的2-异氰基嘧啶，2-酰基苯基异氰酸酯，甚至邻-异氰基苯甲醛
