  无催化剂的Domino Mannich / Friedel-Crafts烷基化反应在合成具有潜在抗肿瘤活性的新型四氢喹啉中的应用

  摘要：

  通过无催化剂的多米诺·曼尼希（Domino Mannich）和N-芳基胺与多聚甲醛和富电子的分子内Friedel-Crafts烷基化反应，已开发出一种有用且有效的方法，以良好的优良率构建各种取代的1,2,3,4-四氢喹啉。烯烃通过形成ñ -芳基- ñ -alkylmethyleneiminium离子作为关键中间体，得到目标产物。在美国国家癌症研究所（NCI）中评估了九种新化合物，其中化合物5f（R1 = 6-MeO，R2 =  p -ClC6H4和X =吡咯烷-2-烯丙基）对57种癌细胞系表现出显着活性，最重要的GI50值范围为1.46至8.28μM体外测定。在HCT116结肠癌细胞上对活性化合物5f进行的进一步研究表明，其对细胞死亡的作用是通过细胞周期停滞（S期）以剂量依赖性方式发挥的，以及对细胞增殖过程的抑制。

• Manganese‐Catalyzed Transfer Hydrogenation of Aldimines
  作者：Duo Wei、Antoine Bruneau‐Voisine、Maxime Dubois、Stéphanie Bastin、Jean‐Baptiste Sortais

  DOI：10.1002/cctc.201900314

  日期：2019.11.7

  The reduction of imines to amines via transfer hydrogenation was achieved promoted by phosphine‐free manganese(I) catalyst. Using isopropanol as reductant, in the presence of tBuOK (4 mol %) and manganese complex [Mn(CO)3Br(κ2N,N‐PyCH2NH2)] (2 mol %), a large variety of aldimines (30 examples) were typically reduced in 3 hours at 80 °C with good to excellent yield.

  不含膦的锰（I）催化剂促进了通过转移氢化将亚胺还原为胺。使用异丙醇作为还原剂，在存在吨丁醇钾（4摩尔％）和锰配合物[锰（CO）3 Br（上κ 2 N，PyCH 2 NH 2）]（2摩尔％），大量的各种醛亚胺的（30个实施例）通常在80°C下经过3小时还原，收率良好至极佳。

• Synthesis and evaluation of a series of benzylaniline hydrochlorides as potential cytotoxic and antimitotic agents acting by inhibition of tubulin polymerization
  作者：Mark Cushman、Hu Ming He、Chii M. Lin、Ernest Hamel

  DOI：10.1021/jm00071a012

  日期：1993.9

  Although certain substituted cis-stilbenes have displayed potent tubulin polymerization inhibitory activity and significant cytotoxicities in cancer cell cultures, these compounds have limited aqueous solubility and are therefore difficult to formulate for in vivo evaluation. A series of water-soluble N-(3,4,5-trimethoxybenzyl)aniline salts has therefore been synthesized in which the olefinic bridge of the stilbenes is replaced by an aminomethylene hydrochloride moiety. A relationship was found between the size of the substituent in the 4-position of the aniline ring and both antitubulin activity and cytotoxicity, such that the smaller the substituent, the greater the potency. The most promising of the newly synthesized compounds was 4-methyl-N-(3,4,5-trimethoxybenzyl)aniline hydrochloride, with an IC50 value of 3.5 muM for inhibition of tubulin polymerization and cytotoxicity for a wide variety of cancer cell lines. The cytotoxicities of the benzylaniline hydrochlorides correlated remarkably well with their antitubulin activities.
