A highly efficient palladium-catalyzed α-arylation of aryloxyketones has been developed, allowing for facile installation of various (hetero)aryl groups at C2 position in good to excellent yields. Subsequent cyclodehydration of the resulting α-arylated aryloxyketones provided rapid access to diverse 2,3-disubstitured benzofurans.
已经开发了一种高效钯催化的芳氧基酮的α-芳基化反应,可以容易地以良好的产率将各种(杂)芳基安装在C2位置。随后的所得α-芳基化芳氧基酮的环脱水作用提供了快速进入各种2,3-二取代的苯并呋喃的途径。
