Vinyl radicals were generated from 3-iodoflavones under a mercury lamp and tandem cyclization reactions occurred with five-membered heteroarenes entailing two consecutive C–C bond formations to synthesize benzo[e]chromeno[2,3-g]indol-13(1H)-one derivatives. The tandem cyclization reactions worked in acetonitrile without any additives such as transition metals, ligands and oxidants, giving rise to a
在汞灯下由3-碘黄酮生成乙烯基自由基,并且与五元杂芳烃发生串联环化反应,需要两个连续的CC键形成,以合成苯并[ e ] chromeno [2,3 - g ]吲哚-13(1 H))-一阶导数。串联环化反应在乙腈中进行,没有任何添加剂,例如过渡金属,配体和氧化剂,在温和且环境友好的反应条件下,以高收率产生了各种各样的新型多环x吨酮骨架。
Methods of stimulating an immune response and treating patients responsive thereto with 3,4-di(1H-indol-3-yl)-1H-pyrrole-2,5-diones, staurosporine analogs, derivatized pyridazines, chromen-4-ones, indolinones, quinazolines, nucleoside analogs, and other small molecules are disclosed. In a preferred embodiment benzopyrimidine derivatives such as ZD-6474, MLN-518, lapatinib, gefitinib or erlotinib are used.
The easily available and efficient catalyst containing a benzimidazolium ligand and PdCl2(PPh3)(2) demonstrated excellent catalytic activity to construct the flavones and aurones, respectively. This reaction can be operated under mild conditions, affording the desired products in moderate to good yields. This protocol was used to prepare the flavones and aurones by a slight modification of amines. (C) 2013 Elsevier Ltd. All rights reserved.
