    An efficient regio- and diastereoselective cyclization of sulfamate-derived cyclic imines with unsubstituted or monosubstituted α-halo hydroxamates is developed under mild conditions. This reaction proceeds smoothly under transition-metal-free conditions via a domino aza-Mannich addition/intramolecular nucleophilic substitution sequence, providing a convenient route to access 2-monosubstituted and
    在温和的条件下,开发了由氨基磺酸衍生的环状亚胺与未取代或单取代的α-卤代异羟肟酸酯进行的高效区域和非对映选择性环化反应。该反应在无过渡金属的条件下通过多米诺氮杂-曼尼希加成/分子内亲核取代序列顺利进行,为获得2-单取代和2,5-二取代的4-咪唑啉酮提供了便利的途径。值得注意的是,产物是用单一反式异构体以中等至优异的产率获得的。

    2,2-dimethylsuccinimidyl radical which subsequently undergoes rin opening to yield Me2ĊCH2C(O)NCO (15). The overall rearrangement of (14) to (15) represents 1,2-shift of the –C(O)NCO group via an intermediate imidyl radical. The glutarimidyl radical is forme by 1,6-endo cyclisation of H2ĊCH2CH2C(O)NCO. It is proposed that the rapid cyclisation of ω-isocyanatoalkyl radicals provides strong evidence

    提出了一种设计胺能GPCR配体的新策略–使用芳族,杂环碱性部分代替常绿哌嗪或脂环族和脂肪族胺。该假设已通过使用一系列基准的5-HT 6 R拮抗剂进行了测试,这些拮抗剂是通过将各种取代的2-氨基咪唑基团偶联至完善的1-苯磺酰基-1 H-吲哚(用作配体核心)而获得的。晶体学研究表明,质子化后,2-氨基咪唑片段触发共振驱动的构象变化,从而导致更高的亲和力。这种分子转换可能是造成5-HT 6差异的原因具有不同胺样片段的化学型的R活性。考虑到嵌入的胍片段的多个功能化位点,构建了各种文库,并建立了结构与活性,代谢稳定性和溶解度之间的关系。N-(1 H-咪唑-2-基)酰基酰胺化学型(10a – z)的化合物对5-HT 6 R表现出高亲和力,对5-HT 1A,5-HT 2A,5-HT 7的选择性很高和D 2受体(结合可忽略不计),这归因于其非常弱的碱性。已显示4-甲基-5- [1-(萘-1-磺酰基)-1 H-吲哚-3-基]
