  • Direct β-acylation of 2-arylidene-1,3-indandiones with acyl chlorides catalyzed by organophosphanes
    作者:Chia-Jui Lee、Chia-Ning Sheu、Cheng-Che Tsai、Zong-Ze Wu、Wenwei Lin
    DOI:10.1039/c3cc45201h

    We have developed an organophosphane-catalyzed direct β-acylation of a series of conjugated systems bearing ketone, amide and ester functionalities using acyl chlorides as trapping reagents. A wide variety of highly functional ketone derivatives were generated efficiently under very mild conditions with high yields according to our protocol. Our adducts can even be utilized as important building blocks for the synthesis of functional tri/tetracyclic pyridazine derivatives.
    我们开发了一种利用膦烷催化剂的直接β-酰基化反应,以一系列含有酮、酰胺和酯官能团的共轭体系为底物,使用酰氯作为捕获试剂。根据我们的方案,在非常温和的条件下,可以高效地生成大量具有高度官能化的酮衍生物,产率很高。我们的加合物甚至可以用作合成含功能性三/四环吡嗪衍生物的重要构建模块。
  • Inhibitory activities against topoisomerase I and II by isoaurostatin derivatives and their structure–activity relationships
    作者:Keitarou Suzuki、Tadashi Okawara、Tatuya Higashijima、Kazumi Yokomizo、Tohru Mizushima、Masami Otsuka

    A (IAS-A) isolated from Thermomonospora alba showed weak inhibition against topoisomerase (topo) I (IC(50)=307microM). To get more strong inhibition, derivatives of IAS-A were prepared and their structure-activity relationships against topo I and II were investigated. The addition of hydroxyl group on aromatic rings increased the activities, 3-(3,4,5-trihydroxybenzylidene)-5-hydroxy-3H-benzofuran-2-one
    从白热单孢菌中分离得到的异潮红素A(IAS-A)对拓扑异构酶(topo)I的抑制作用较弱(IC(50)= 307microM)。为了获得更强的抑制作用,制备了IAS-A衍生物,并研究了它们对topo I和II的构效关系。芳香环上羟基的添加增加了活性,3-(3,4,5-三羟基亚苄基)-5-羟基-3H-苯并呋喃-2-酮(IAS-9)表现出较强的抑制作用(IC(50)= 3microM ),同时增加羟基对多种癌细胞的生长抑制作用,而IAS-9表现出最强的抑制作用。与喜树碱和依托泊苷不同,IAS-9既不能稳定DNA-拓扑可裂解的复合物,也不能插入DNA中,并且非竞争性地抑制了topo I和II。
  • 2-(2-Hydroxyaryl)cinnamic amides: a new class of axially chiral molecules
    作者:Chiara Marelli、Chiara Monti、Simona Galli、Norberto Masciocchi、Umberto Piarulli
    DOI:10.1016/j.tet.2006.07.019
    日期:2006.9
    The syntheses of several differently substituted amides formally derived from a chiral amine, either E-2-(2-hydroxyphenyl)cinnamic acid or both E- and Z-2-(2-hydroxynaphthyl)cinnamic acid, are reported. These molecules display a restricted rotation about the C-2-(aryl) bond. The barriers to rotation about the C-2-(aryl) bond were measured by the dynamic H-1 NMR and were found to vary between 11.8 and 24.5 kcal mol(-1), depending on the substitution. In particular, E-2-(2-hydroxynapthyl)cinnamic amides, displayed a high barrier to rotation (Delta G(c)(double dagger)= 24.4 kcal mol(-1)) and could be isolated in both diastereomerically pure forms at room temperature. The X-ray structure of one E-2-(2-hydroxynapthyl)cinnamic amide, was resolved, enabling for the determination of the absolute configuration of the chiral axis (aR). (c) 2006 Elsevier Ltd.
