Abstract 4-Trimethylstannylcoumarins 2, conveniently obtained from the corresponding 4-triflyloxycoumarins 1, undergo Pd(0)/CuI-cocatalyzed cross-coupling reactions with a variety of aryl iodides to afford 4-arylcoumarins 4 in moderate to good yields. Aryl triflates are less effective as coupling partners.
摘要 4-三甲基甲锡基香豆素 2 可方便地从相应的 4-三氟甲氧基香豆素 1 中获得,与各种芳基碘化物进行 Pd(0)/CuI 共催化的交叉偶联反应,以中等至良好的产率得到 4-芳基香豆素 4。芳基三氟甲磺酸酯作为偶联伙伴的效果较差。
