  Synthesis and SAR of novel di- and trisubstituted 1,4-dihydroquinoxaline-2,3-diones related to licostinel (Acea 1021) as NMDA/glycine site antagonists

  摘要：

  A series of novel di- and trisubstituted 1,4-dihydroquinoxaline-2,3-diones (QXs) related to licostinel (Acea 1021) was synthesized and evaluated as antagonists for the glycine site of the N-methyl-D-asparate (NMDA) receptor. The in vitro potency of these antagonists was determined by displacement of the glycine site radioligand [H-3]-5,7-dichlorokynurenic acid ([H-3]DCKA) in rat brain cortical membranes. Structure-activity relationship studies indicate that a cyano group is a good replacement for the nitro group in the 5-position of licostinel while 5-carboxy, 5-ester, 5-ketone and 5-amide derivatives showed reduced potency. 5,6-Cyclized analogues of licostinel also showed significantly reduced potency. Among the trisubstituted QXs investigated, 5-cyano-6,7-dichloro QX and 5-cyano-7-chloro-6-methyl QX are the most potent with IC50 values of 32 nM and 26 nM, respectively.

• A New, Efficient Glycosylation Method for Oligosaccharide Synthesis under Neutral Conditions:  Preparation and Use of New DISAL Donors
  作者：Lars Petersen、Knud J. Jensen

  DOI：10.1021/jo0057654

  日期：2001.9.1

  Efficient, stereoselective glycosylation methods are required for the synthesis of complex oligosaccharides as tools in glycobiology. All glycosylation methods, which have found wide acceptance, rely on Lewis acid activation of glycosyl donors prior to glycosylation. Here, we present a new and efficient method for glycosylation under neutral or mildly basic conditions. Glycosides of methyl 2-hydroxy-3

  需要高效，立体选择性的糖基化方法来合成复杂的寡糖，并将其作为糖生物学的工具。已经被广泛接受的所有糖基化方法都依赖于糖基化之前糖基供体的路易斯酸活化。在这里，我们提出了一种在中性或轻度碱性条件下糖基化的新方法。通过亲核芳族取代制备2-羟基-3,5-二硝基苯甲酸甲酯（DISAL）及其对位异构体4-羟基-3,5-二硝基苯甲酸甲酯的糖苷。在它们作为糖基供体的潜力的第一个证明中，实现了甲醇的立体定向糖基化。在受阻醇的糖基化反应中，β-给体被证明具有更高的反应性，并且主要形成了α-葡萄糖苷。被保护的单糖的糖基化，在没有路易斯酸和碱的情况下，在40-60℃下于1-甲基-2-吡咯烷酮（NMP）中平稳地进行与游离的6-OH或3-OH的反应，获得了良好的产率。3-OH的糖基化仅产生α-连接的二糖。
• Reconsidering glycosylations at high temperature: precise microwave heating
  作者：Kim Larsen、Kasper Worm-Leonhard、Peter Olsen、Andreas Hoel、Knud J. Jensen

  DOI：10.1039/b511266d

  日期：——

  Current methods for glycosylation of complex alcohols, e.g. with glycosyl trichloroacetimidates, generally occur in the presence of a strong Lewis acid ‘promoter’, and at sub-ambient temperatures. However, the older literature reports high-temperature glycosylations, especially of phenols. We have described an efficient method for glycosylation of alcohols under neutral conditions, using as anomeric leaving group methyl 3,5-dinitrosalicylate (DISAL). Only a very few reports have described the use of microwaves to promote glycosylations, mainly of simple alcohols. Here we describe fast, high-temperature glycosylations using precise microwave heating in the synthesis of oligosaccharides, with both DISAL and widely used trichloroacetimidate glycosyl donors in the absence of strong Lewis acids. Also, we have applied microwave heating as a general protocol for evaluating new, potential glycosyl donors.

  目前用于复杂醇类（如使用糖基三氯乙酰亚胺酸酯）的糖基化方法通常在强Lewis酸“促进剂”存在下，并在亚环境温度下进行。然而，早期的文献报道了高温下的糖基化反应，特别是酚类的糖基化。我们已经描述了一种在中性条件下使用异头离去基团甲基3,5-二硝基水杨酸酯（DISAL）进行醇类糖基化的高效方法。仅有极少数报道描述了使用微波促进糖基化反应，主要是简单醇类。在这里，我们描述了在不含强Lewis酸的情况下，使用精确微波加热在寡糖合成中进行快速、高温糖基化反应，同时使用DISAL和广泛应用的三氯乙酰亚胺酸酯糖基供体。此外，我们还将微波加热作为一种通用协议，用于评估新的潜在糖基供体。
