Photolysis of 4-azidopyridines (7a-e) in the presence of methoxide ions resulted in ring expansion to give 5-methoxy-6H-1,4-diazepines (10a-e), presumably via the azirine intermediates 8 derived from the initially formed singlet pyridylnitrenes.Treatment
PHOTOLYSIS OF PYRIDYL AZIDES IN THE PRESENCE OF METHOXIDE IONS: FORMATION OF FULLY UNSATURATED 1,3- AND 1,4-DIAZEPINES

, p. 4694 - 4697 (2007/10/02)
Photolysis of 4-azidopyridines (1) in the presence of methoxide ions resulted in ring-expansion to give the 6H-1,4-diazepines (4).Treatment of the diazepine (4a) with benzoyl chloride afforded the 1-benzoyl-1H-1,4-diazepine (5), whose structure was confir
