  • C-1 Alkynylation of N-Methyltetrahydroisoquinolines through CDC: A Direct Access to Phenethylisoquinoline Alkaloids
    作者:Kamal Singh、Paramjit Singh、Amarjit Kaur、Pushpinder Singh
    DOI:10.1055/s-0031-1290532
    日期:2012.3
    Direct cross-coupling between N-methyltetrahydroisoquinolines and alkynes using CuI-DEAD is presented. It affords the regioselective C-1-alkynylated products in good yield. This regio­selectivity is in contrast to the results reported earlier in the reaction of N,N-dimethylbenzyl amine where the N-methyl alkynylated product was formed exclusively or predominantly. The C-1-substituted propargylic isoquinolines were easily reduced to phenethylisoquinolines with Pd/C. This reaction sequence provides a short route to synthesize methopholine, homolaudanosine and other phenethylisoquinoline alkaloids.
    本文介绍了一种使用CuI-DEAD的N-甲基四氢异喹啉与炔烃之间的直接交叉偶联反应,该反应以高产率选择性地生成了C-1位炔基化的产物。这种区域选择性与先前报道的N,N-二甲基苄胺反应结果形成鲜明对比,后者几乎完全或主要生成N-甲基炔基化产物。C-1位取代的丙炔基异喹啉能通过Pd/C催化轻易还原为苯乙基异喹啉。这一反应序列提供了一条合成甲氧啡啉、同劳丹诺素及其他苯乙基异喹啉生物碱的简捷途径。
  • Unified Approach to Isoindolinones and THIQs via Lewis Acid Catalyzed Domino Mukaiyama–Mannich Lactamization/Alkylations: Application in the Synthesis of (±)-Homolaudanosine
    作者:Sivasankaran Dhanasekaran、Anirban Kayet、Arun Suneja、Vishnumaya Bisai、Vinod K. Singh

    variety of isoindolinones and tetrahydroisoquinolines via a Lewis acid catalyzed domino Mukaiyama–Mannich lactamization/alkylation is achieved. This transformation comprises a sequential formation of three new bonds through a one-pot, three-component procedure to afford product in moderate to high yields. A concise synthesis of (±)-homolaudanosine (2b) has been achieved using this method.

  • Conservation of the deleted-in-azoospermia-like-1 (DAZL1) gene structure in old world monkeys points to a homologous function of DAZL1 in this primate class

    displayed a similar conservation as their coding regions (i.e. 91-94%). Both belong to the primate class of old world monkeys evolutionarily separated 36-55 million years ago (1). The strong conservation of the complete DAZL1 gene structure in both primate species suggests a similar control and maturation pathway of DAZL1 transcripts in the germ line of old world monkeys and also indicates a homologous
    我们分离了旧猴猴猕猴(暂时定名为MafaDAZL1)的完整的无精子样1(DAZL1)基因,并将其序列结构与迄今为止分离的其他DAZL1基因进行了比较。除了同源的RNA识别基序(RRM域),我们只发现Mafa-DAZL1编码区对哺乳动物DAZL1基因(即小鼠:Dazl1;人:DAZL1)和非洲爪蟾(xdazl)的高度保守。 。仅在灵长类动物,猕猴和人中,5'和3'非翻译DAZL1基因结构(UTR)的序列和长度显示出与其编码区相似的保守性(即91-94%)。它们都属于在36-55百万年前进化分开的旧世界猴子的灵长类动物类别(1)。
  • Succinct Syntheses of Methopholine, (±)‐Homolaudanosine, and (±)‐Dysoxyline via Metal‐free One‐Pot Double Alkylation on 1‐Methyl‐3,4‐dihydroisoquinolines
    作者:Raghavendra Achary、Seulgi Kim、Yuri Choi、Gangadhar Rao Mathi、Hyun Jin Kim、Jong Yeon Hwang、Pilho Kim
    DOI:10.1002/bkcs.11677
    日期:2019.3
    A mild one‐pot and metal‐free condition was discovered to implement two different alkyl groups chemoselectively on 1methyl‐3,4‐dihydroisoquinoline (1‐Me‐DHIQ), one at the nitrogen another at the C1‐methyl group. This chemistry is compatible with various DHIQs as well as alkyl halides. Application of this chemistry facilitated the concise syntheses of methopholine, (±)‐homolaudanosine, and (±)‐dysoxyline

  • Synthesis and Radioligand Binding Studies of Methoxylated 1,2,3,4-Tetrahydroisoquinolinium Derivatives as Ligands of the Apamin-Sensitive Ca<sup>2+</sup>-Activated K<sup>+</sup> Channels
    作者:Amaury Graulich、Jacqueline Scuvée-Moreau、Livia Alleva、Cédric Lamy、Olivier Waroux、Vincent Seutin、Jean-François Liégeois
    DOI:10.1021/jm0607395
    日期:2006.11.30
    Several methoxylated 1,2,3,4-tetrahydroisoquinoliniums derived from N-methyl-laudanosine and N-methyl-noscapine were synthesized and evaluated for their affinity for apamin-sensitive binding sites. The quaternary ammonium derivatives have a higher affinity with regard to the tertiary amines. 6,7-Dimethoxy analogues possess a higher affinity than the 6,8- and 7,8- dimethoxy isomers. A 3,4-dimethoxybenzyl or a 2-naphthylmethyl moiety in C-1 position are more favorable than a 3,4-dimethoxyphenethyl group. Smaller groups such as propyl or isobutyl are unfavorable. In 6,7-dimethoxy analogues, increasing the size and lipophilicity with a naphthyl group in the C-1 position leads to a slight increase of affinity, while the same group in the 6,7,8- trimethoxy series is less favorable. The 6,7,8- trimethoxy derivative 3f is the first tertiary amine in the series to possess an affinity close to that of N-methyl-laudanosine and N-methyl-noscapine. Moreover, electrophysiological studies show that the most effective compound 4f blocks the apamin-sensitive afterhyperpolarization in rat dopaminergic neurons.
