On the pyrazine and pyrazine–pyrimidine dimers

The Journal of Chemical Physics, 1986
Spectra of the pyrazine-d4, pyrazine-h4–pyrazine-d4, and pyrazine-d4–pyrimidine dimer are obtained and analyzed with the help of Lennard-Jones–hydrogen-bonding (LJ–HB) potential energy calculations. The pyrazine isotopic hetero and homo dimers possess nearly identical spectra with the exception that the perpendicular dimer features are displaced to the

Pyrazine Analogues of Dipyrrolylquinoxalines

Organic Letters, 2003
[structure: see text]. The synthesis of novel pyrazine derivatives bearing pyrrolic substituents is reported; the ability of these systems to bind certain biologically relevant anions in dichloromethane is also detailed.

Microbial metabolism of pyrazines

Critical Reviews in Microbiology, 2011
Pyrazines are a group of 1,4 dinitrogen substituted benzenes. They have near ubiquitous biological distribution and majority are anthropogenic. The demand for pyrazines in the recent years has increased owing to their vast applications in the field of food, agriculture and medicine.

Vibrational spectra of [1H4]pyrazine and [2H4]pyrazine

Journal of the Chemical Society, Faraday Transactions 2, 1985
Infrared and Raman spectra of [1H4]pyrazine and [2H4]pyrazine have been reinvestigated and a general assignment of all the observed bands is proposed which modifies some previous assignments of fundamental vibrations. The present assignment satisfies the isotopic product rule for i.r.- and Raman-active fundamentals.

Speculating about pyrazines

Proceedings of the Royal Society of London. Series B: Biological Sciences, 1990
Of the various types of alerting signals found in nature, odours are the least well understood. The worldwide distribution of pyrazines in plants, insects, terrestrial vertebrates, marine organisms, fungi and bacteria suggests that they are of special significance.
