The microwave irradiation of a series of 2-diazo-1,3-diketones in the presence of an o-phenylenediamine derivative triggered a domino Wolff rearrangement/nucleophilic addition/intramolecular imination sequence to provide a new synthetic entry to 1,3-dihydr-2H-1,5-benzodiazepin-2-ones, a class of molecules with important biological properties.
在邻苯二胺衍生物的存在下,一系列 2-重氮-1,3-二酮的微波辐射触发了多米诺沃尔夫重排/亲核加成/分子内亚胺化序列,为 1,3-二氢- 2H-1,5-benzodiazepin-2-ones,一类具有重要生物学特性的分子。
