A new method is proposed for the preparation of 2-aroylbenzofurans and 2-aroylnaphtho[2,1-b]furans via oxidative rearrangement of 2,4-diaryl-4Н-chromenes and 1,3-diaryl-1Н-benzo[f]chromenes in the presence of selenium dioxide.
提出了一种新的制备2-芳基苯并呋喃和2-芳基萘并[2,1- b ]呋喃的新方法,该方法通过氧化2,4-二芳基-4Н-色烯和1,3-二芳基-1Н-苯并[]在二氧化硒存在下的f ]色酮。
