    Modified Pictet–Spengler reaction. A highly diastereoselective approach to 1,2,3-trisubstituted-1,2,3,4-tetrahydro-β-carbolines using perhydro-1,3-heterocycles
    摘要:
    A flexible variant of the Pictet-Spengler reaction employing oxazinanes as synthetic equivalents of several carbonyl compounds has been developed. Using acid catalyzed one pot condensation of perhydro-1,3-heterocycles various 1,3-disubstituted and 1,2,3-trisubstituted-1,2,3,4-tetrahydro-beta -carbolines (THBCs) have been synthesized diastereoselectively.

  • Synthesis, activation, and cytotoxicity of aldophosphamide analogs
    作者:Richard F. Borch、Ronald R. Valente
    DOI:10.1021/jm00114a014
    日期:1991.10
    tautomerization to an enamine intermediate might provide a mechanistic alternative to the beta-elimination reaction for release of phosphoramide mustard. The 4,4,6-trimethyltetrahydro-1,3-oxazine moiety was selected on the basis of its rapid rate of iminium ion generation and relatively slow rate of hydrolysis. These analogues underwent phosphorodiamidate release by three distinct mechanisms: hydrolysis to aldophosphamide
    制备了一系列醛酰胺的全氢恶嗪类似物,并对其31P NMR动力学和体外细胞毒性进行了评估。这些化合物是基于这样的想法而开发的,即开环和互变异构化为烯胺中间体可能为释放酰胺芥菜的β-消除反应提供一种机械替代方法。选择4,4,6-三甲基四氢-1,3-恶嗪部分是基于其亚胺离子生成速度快和解速度相对慢的原因。这些类似物通过三种不同的机制释放二氨基磷酸酯:解为醛基磷酸酰胺和随后的β-消除;环化生成4-羟基环酰胺,该环酰胺通过开环和消除作用释放二氨基磷酸酯;并通过快速排出二磷酸酯而互变为烯胺。动力学研究表明,解成醛对整个活化过程的贡献最小,烯胺途径代表了活化的主要途径。对于那些可能经历环化的类似物,该途径与烯胺释放有效竞争,并且这些类似物在细胞毒性上基本上等同于它们的4-羟基环酰胺。制备了一系列不能进行环化的四-N-取代的磷酸氨基甲酸酯,以探索环化对这些类似物的细胞毒性的影响。
  • An expedient protocol of the Biginelli dihydropyrimidine synthesis using carbonyl equivalents
    作者:Kamaljit Singh、Jasbir Singh、Prasant K. Deb、Harjit Singh
    DOI:10.1016/s0040-4020(99)00760-7
    日期:1999.10
    A one - pot condensation of perhydro-1,3 heterocycles - aldehyde equivalents with ethyl acetoacetate and ureas provides a convenient synthesis of the title compounds with a variety of substituents at C-4. Yields are equivalent or significantly higher than the conventional methods.

  • Pictet–Spengler reaction: is carbonyl the best choice? A highly diastereoselective alternative approach to trans-1,3-disubstituted tetrahydro-β-carbolines
    作者:Kamaljit Singh、Prasant K Deb
    DOI:10.1016/s0040-4039(00)00751-6
    日期:2000.6
    Unprecedented 1,2,3-trisubstituted tetrahydro-beta-carbolines (THBCs) have been synthesized via a short and highly diastereoselective synthetic route. The key step of the sequence is a flexible variant of the Pictet-Spengler reaction employing synthetic equivalents of several non-available carbonyl compounds. Using one such synthon, the resultant THBC could be further ring-closed to a tetracyclic indole alkaloidal skeleton. (C) 2000 Elsevier Science Ltd. All rights reserved.
