  • A Convenient Palladium‐Catalyzed Carbonylative Synthesis of (<i>E</i>)‐3‐Benzylidenechroman‐4‐ones
    作者:Wei‐Feng Wang、Jin‐Bao Peng、Xinxin Qi、Jun Ying、Xiao‐Feng Wu

    A convenient palladium‐catalyzed carbonylation reaction for the efficient synthesis of (E)‐3‐benzylidenechroman‐4‐ones has been developed. Using TFBen as a solid CO source, a range of substituted (E)‐3‐benzylidenechroman‐4‐ones were prepared in moderate to good yields with 2‐iodophenols and allyl chlorides as the substrates. Additionally, substituted quinolin‐4(1H)‐ones can also be obtained with 2‐iodoaniline
    已经开发了一种便捷的钯催化羰基化反应,可有效合成(E)-3-亚苄基苯并二氢吡喃-4-酮。使用TFBen作为固体CO源,以2-碘苯酚和烯丙基氯为底物,以中等至良好的收率制备了一系列取代的(E)-3-苄叉基苯并四氢吡喃-4-酮。另外,也可以以2-碘苯胺为起始原料获得取代的喹啉-4(1 H)-1 。
