  Modifications to the Tetracaine Scaffold Produce Cyclic Nucleotide-Gated Channel Blockers with Widely Varying Efficacies

  摘要：

  Five new tetracaine analogues were synthesized and evaluated for potency of blockade of cyclic nucleotide-gated channels relative to a multiply charged tetracaine analogue described previously (4). Increased positive charge at the tertiary amine end of tetracaine results in higher potency and voltage dependence of block. Modifications that reduce the hydrophobic character at the butyl tail are deleterious to block. The tetracaine analogues described here have apparent affinities for CNGA1 channels that vary over nearly 8 orders of magnitude.

  and related seven-membered heterocyclic amidines 4. Compounds 1 were synthesized by Cs2CO3/KI-mediated aminolysis of 4-chlorobutyronitrile and subsequent reduction. N-Acylation of diamines 1 with carboxylic acid anhydrides led selectively to N-acyl-N′-aryl tetramethylenediamines 3. Microwave-assisted ring closure of such precursors promoted by PPE allowed for the synthesis of hitherto unreported 1-aryl-2-alkyl-1H-1

  在本函中，我们报道了使用N-芳基腐胺作为合成中间体，用于制备N-酰基-N'-芳基四亚甲基二胺3和相关的七元杂环am 4。通过Cs 2 CO 3 / KI介导的4-氯丁腈的氨解并随后还原来合成化合物1。二胺1与羧酸酐的N-酰化选择性地导致N-酰基-N'-芳基四亚甲基二胺3。由PPE促进的此类前体的微波辅助闭环反应允许合成迄今未报道的1-芳基-2-烷基-1 H -1,4,5,6-四氢-1,3-二氮杂4。

  We present a two-step, general synthesis of N-aryl­putrescines and cadaverines, by cesium carbonate mediated alkylation of anilines with ω-chloronitriles and subsequent reduction. The cesium-mediated alkylation shows remarkable selectivity towards the monoalkylation product. The method is straightforward and leads to satisfactory global yields.

  我们介绍了一种通过碳酸铯介导的苯胺与Ï-氯腈的烷基化反应以及随后的还原反应，分两步合成 N-芳基putrescines 和adaverines 的通用方法。铯介导的烷基化反应对单烷基化产物具有显著的选择性。该方法简便易行，并能获得令人满意的总产率。
