, p. 885 - 888 (2007/10/02)
Azidopyrazines bearing amino, methoxy and/or phenylgroups have been synthesized by reaction of pyrazine N-oxides with trimethylsilyl azide in the presence of diethylcarbamoyl chloride in refluxing acetonitrile.In most cases, the azidation occurs only at t
Synthesis of Some Alkyl- and Arylimidazoles
Watanabe, T.,Nishiyama, J.,Hirate, R.,Uehara, K.,Inoue, M.,et al.
, p. 1277 - 1281 (2007/10/02)
The pyrolysis of 2-azidopyrazines led to give 1-cyanoimidazoles, which were hydrolyzed in alkaline and acidic media to the corresponding imidazoles.This ring transformation occured also by photolysis.

, p. 1963 - 1966 (2007/10/02)
The pyrolysis of 2-azido-3,5- (IIa), 2-azido-3,6- (IIb), and 2-azido-5,6-dipheny;pyrazines (IIc), prepared from the corresponding 2-chloro-diphenylpyrazines and sodium azide, led respectively to 1-cyano-diphenylimidazoles (IIIa, IIIb, and IIIc) in good yi
