A novel ring transformation of 5-azidothiazoles

Ceulemans, Erik,Dyall, Leonard K.,Dehaen, Wim

, p. 1977 - 1988 (2007/10/03)

The 4-oxoalkyl- and 4-iminoalkyl-5-azidothiazoles undergo a ring transformation with nitrogen loss at relatively low temperatures to afford 4- cyanooxazoles and 4-cyanoimidazoles, respectively. The mechanism, which is thought to involve a ring opening-ring closure process, is discussed.
