8-diaminonaphthalene (2) to form the diazaphosphinines (3a and 3b). They were further reacted with different alkyl azides (4a-e) in THF at 50-55 °C under N2 atmosphere to afford the corresponding iminophosphoranes (5a-j). Their structures were established by elemental analysis, IR, 1H, 13C, 31P NMR and Mass spectral data. All of them exhibited moderate antibacterial activity.
通过两步法合成标题化合物(5a-j)。使4-氯苯基和双(2-氯乙基)氨基-二溴亚磷酸酯(1a和1b)与1,8-二氨基萘(2)反应形成二氮膦(3a和3b)。使它们与不同的烷基叠氮化物(4a-e)在THF中在N 2气氛下于50-55°C反应,得到相应的亚氨基正膦(5a-j)。通过元素分析IR,1 H,13 C,31建立了它们的结构1 H NMR和质谱数据。它们均显示出中等的抗菌活性。

Nitro compounds are known to change reaction rates and kinetic concentration dependence of Brønsted‐acid‐catalyzed reactions. Yet, no mechanistic model exists to account for these observations. In this work, an atomistic model for the catalytically active form for an alcohol dehydroazidation reaction is presented, which is generated by DFT calculations and consists of an H‐bonded aggregate of two molecules
Homocamptothecin is emerging as an important topoisomerase I inhibitor originating in natural product camptothecin. We report the modifications and SAR of homocamptothecin on position C10 to develop potent topoisomerase I inhibitors for anticancer drug discovery. Based on click chemistry, twenty‐one 1,2,3‐triazole‐substituted homocamptothecin derivatives were readily synthesized in two steps. For A549
喜树碱是一种重要的拓扑异构酶I抑制剂,起源于喜树碱天然产物。我们报道了C10位置上喜树碱的修饰和SAR,以开发有效的拓扑异构酶I抑制剂用于抗癌药物的发现。根据点击化学,可以很容易地通过两个步骤合成二十一种1,2,3-三唑取代的同型喜树碱衍生物。对于A549,环烷基和烷基取代的化合物6j,6l和6o表现出高度的抗增殖抑制活性,IC 50值分别为30、30和50 n m。此外,环丙基6j的Topo I抑制活性高于20(S)喜树碱,表明适合进一步药物开发。
