This supplement reflects and emphasizes current research trends. Due to the vast increase in the number and types of individual quinazolines described in recent literature, the author has replaced the myriad classified tables of known quinazolines with a single alphabetical table of simple known quinazolines. To facilitate recovery of any earlier data from the tables in the original volume, a cross-reference has been added (when appropriate) to each individual entry in the new table. Contains an extensive chapter on primary syntheses.

This new volume substantially updates the original pyridazines volume which was published in 1973. Announcing the latest volume in the successful and prominent Chemistry of Heterocyclic Compounds Series.

This book serves as a supplement to The Pyrazines, Volume 41 of the Chemistry of Heterocyclic Compounds series. It covers the literature published between 1979 and 2000, and-together with Volume 41-provides a complete, up-to-date reference for heterocyclic chemists. It emphasizes practical approaches to pyrazine chemistry, offers a full appendix of all simple pyrazines up to 2000, and features detailed coverage of the following topics:

• Systematic descriptions of all primary synthetic routes to pyrazines
  
• Other preparative routes to alkylpyrazines and their...

Drawing from over 2,500 papers, this volume eliminates the need for time-consuming literature surveys for pyrimidines from 1970 through 1983. Chapters summarize the major advances in pyrimidine chemistry, detail advances in methods of primary synthesis of pyrimidines, update all aspects of hydropyrimidines, and treat recent advances in the ionization and spectra of pyrimidines.
