| 摘 要： | Dihydro-1-benzoyl-1,5-benzodiazepines react with (ethoxycarbonyl)carbenes to give 4H-azirino-1,2-a]1,5]-benzodiazepines and unexpected new tin9 system 1H-pyrrolo-1,2-a]1,5]-benzodiazepines. Dihydro-1,5-benzothiazepines react with (ethoxycarbonyl)carbenes in cyclohexane to gire unexpected rin9 cleavage products ethyl (2E, 4E)-3-aryl-2-arylthiohexadienoates.

| Abstract: | Dihydro-1-benzoyl-1,5-benzodiazepines react with (ethoxycarbonyl)carbenes to give 4H-azirino-1,2-a] 1,5]-benzodiazepines and unexpected new ring system 1H-pyrrolo-1,2-a] 1,5]-benzodiazepines. Dihydro-1,5-benzothiazepines react with (ethoxycarbonyl)carbenes in cyclohexane to gire unexpected ring cleavage products ethyl (2E, 4E)-3-aryl-2-arylthiohexadienoates. |
