通过添加以下化合物合成了一系列炔丙醇 苯乙炔到Isatin及其N-取代的衍生物。该反应涉及通过与表现为“配体样”的羰基底物的配位来活化锌试剂。研究了这些化合物对H 2 O 2诱导的PC12细胞凋亡的保护作用的生物活性以及对这些化合物对肺癌A549和P388细胞系的细胞毒性,并且几种化合物均显示出有效的活性。杂环化学杂志,46,217(2009)。
Synthesis of 3-ethynyl-3-hydroxy-2-oxindoles and 3-hydroxy-3-(indol-3-yl) indolin-2-ones using CuWO4 nanoparticles as recyclable heterogeneous catalyst in aqueous medium
acetylenes (spC-H activation) and selective synthesis of 3-hydroxy-3-(indol-3-yl) indolin-2-ones and 3,3′-bis(indolyl)indolin-2-ones (via Friedel-Crafts alkylation reaction) is reported in presence of CuWO4 (10 mol%) nanoparticles in aqueous medium. The catalyst was regenerated and reused up to 6 cycles without losing catalytic activity. This is the first report for the spC-H activation using CuWO4
