Upon exposure to singlet oxygen and dimethylsulfide, the addition products between 3-furaldehydes and Grignard reagents undergo an oxidative rearrangement to give 2-substituted 3-furaldehydes, in yields ranging from 26-83%. N-Aryl- and N-tosylpyrroles were similarly obtained if the corresponding nitrogen-containing precursors were used instead, in equally attractive yields (64-92%).
接触单线态氧和二甲基硫醚后,3-呋喃醛与格氏试剂的加成产物发生氧化重排,生成 2-取代的 3-呋喃醛,产率为 26-83%。如果使用相应的含氮前体,同样可以得到 N-芳基和 N-对甲苯磺酰基吡咯,收率同样诱人(64-92%)。
