Photolysis of the quinoline N-imides (3) having an electron-donating substituent in the 6- or 8-position affords the corresponding 3H-1,3-benzodiazepines (4), whereas quinolines having an electron-donating group in the other positions or an electron-withdrawing group give no diazepines.
对在6或8位具有供电子取代基的喹啉N-酰亚胺(3)进行光解可得到相应的3 H -1,3-苯并二氮杂卓(4),而在另一方具有供电子基团的喹啉位置或吸电子基团不产生二氮杂s。
