[PDF] The Chemistry of Heterocyclic Compounds, Condensed Pyrazines G. W. H. Chesseman, R. F. Cookson

Provides an account of the preparation, properties, and uses of the more important bi- and tri-cyclic ring systems incorporating the pyrazine ring. The first 18 chapters survey the developments in the chemistry of quinoxalines since the appearance in 1953 of a previous monograph in this series. The subsequent 22 chapters provide the first authoritative reviews of the chemistry of such important related ring systems as the pyrrolopyrazines.
