Reinvestigation of Rearrangement of Benzodiazepinediones into Quinoleines Under Microwave or Conventional Heating Conditions
摘要:
Microwave or conventional heating of pyrrolo and pyrido[2,1-c][1,4]benzodiazepines in boiling phosphorus oxychloride led to rearranged products like benzo[h][1,6]naphthyridine and azepino[3,2-c]quinoleine and not to cyclopenta[b] [1,6]benzodiazepin and tetrahydrodibenzo[b,f][1,4]diazepine as initially described.

Microwave heating of pyrrolo and pyrido[2,1-c][1,4]benzodiazepine-diones in boiling phosphorus oxychloride produced a new rearrangement leading to cyclopenta[b][1,4]benzodiazepines and tetrahydrodibenzo[b,f][1,4]diazepines respectively.
微波加热沸腾的三氯氧化磷中的吡咯并吡啶并[2,1- c ] [1,4]苯并二氮杂二酮产生新的重排,导致环戊[ b ] [1,4]苯并二氮杂和四氢二苯并[ b,f ] [1 ,4]二氮杂s。
