New Method of Synthesis and Biological Evaluation of Some Combretastatin A-4 Analogues
摘要:
A series of novel combretastatin A-4 analogues was synthesized in 36-64% yields by Negishi cross-coupling reaction under mild conditions. The prepared compounds exhibit good cytotoxicity against HBL100 epithelial cell lines (IC50 = 0.022-10.31 mu M).

The synthesis of aryl amines via the formation of a C−N bond is an essential tool for the preparation of functional materials, active pharmaceutical ingredients and bioactive products. Usually, this chemical connection is only possible by transition metal-catalyzed reactions, photochemistry or electrochemistry. Here, we report a metal-free arene C−H amination using hydroxylamine derivatives under benign
