The Schmidt and Beckmann rearrangement of 3,4-dihydro-4,4-dimethyl-1(2H)-naphthalenones bearing oxygenated groups at the 5,8-positions, and some of their oximes are reported. Depending upon the structure of the substrates and the reaction conditions 4,5-dihydro-3H-naphth[1,8-cd]isoxazol, benzazepin-2-one and 5,6-dihydro-7H-tetrazolo[1,5-a][2]benzazepine derivatives were generated.
据报道,在5,8-位带有氧化基团的3,4-二氢-4,4-二甲基-1(2 H)-萘烯的Schmidt和Beckmann重排及其某些肟。取决于底物的结构和反应条件,4,5-二氢-3 H-萘[1,8- cd ]异恶唑,苯并enza庚因-2-酮和5,6-二氢-7 H-四唑[1,5] -产生了[] [2]苯并ze庚因衍生物。
