报道了3-芳基丙酸在PIFA或氧酮作用下的直接氧化环化反应。在BF(3)中心点OEt(2)存在下,3-芳基丙酸与PIFA或氧酮在30℃下反应顺利,以较好的产率得到3,4-二氢香豆素。(C)2009爱思唯尔有限公司。保留所有权利。
The direct oxidative cyclization of 3-arylpropionic acids using PIFA or Oxone is reported. In the presence of BF(3)center dot OEt(2), the reaction of 3-arylpropionic acids with PIFA or Oxone proceeded smoothly at 30 degrees C to give 3,4-dihydrocoumarins in good to excellent yields.
