  • Synthesis and anti-tubulin evaluation of chromone-based analogues of combretastatins
    作者:Jérôme Quintin、Catherine Roullier、Sylviane Thoret、Guy Lewin
    DOI:10.1016/j.tet.2006.02.024
    日期:2006.4
    Twenty new hybrid compounds with both combretastatin and flavone moieties were synthesized. These derivatives are classified according to the position of the trimethoxyphenyl ring at C-2 or C-3 of the chromone and presence or absence of a carbonyl as a linker between C-3 and the aryl ring. Most of these compounds were prepared from hesperidin or naringin, two natural and abundant Citrus flavonoids. Seven of these combretastatin analogues revealed anti-tubulin activity but in a medium range. (c) 2006 Elsevier Ltd. All rights reserved.

    An efficient and regioselective hydrodehalogenation of aromatic α‐ and β‐halo carbonyl compounds has been developed using CuI in isopropanol under basic condition. This reaction system effectively reduces chloride, bromide and iodide groups and affords high yield (up to 97 %) as carbonyl compounds. The method is environmentally friendly and demonstrates excellent tolerance to a broad range of electronically
