摘要：

Quinazoline 3-oxides 1 are photoisomerized to benzo [f]-1,3,5-oxadiazepines 2. 6-Chloro-2-methyl-4-phenylquinazoline 1-oxide (4) gives 1-acetyl-5-chloro-3-phenylindazole (6) on irradiation. 7-Chloro-2-methylamino-5-phenyl-3H-1,4-benzodiazepine 3-oxide (9) gives a mixture of 9-chloro-5-methylamino-2-phenyl-4H-benzo[g]-1,3,6-oxadiazocine (11) and 1-benzoyl-7-chloro-1,2-dihydro-3-methylaminoquinoxaline (12a). These transformations are believed to proceed by rearrangement of the oxaziridines formed as primary isomerization products. © 1968, American Chemical Society. All rights reserved.
