This volume in the Chemistry of Heterocyclic Compounds series presents a comprehensive review of the quinoxaline literature from 1975 to the present (2002), updating Volumes 5 and 35. It provides an alphabetical table of known simple quinoxalines, including new compounds discussed in this volume and their physical data, as well as the pyrazines from the original volumes. Biological activities, spectral or other physical studies, and other such materials appear at appropriate points in the text. The in-depth coverage includes synthesis, reactions, spectroscopic, and physical properties for each class of compounds. Chemistry of Heterocyclic Compounds, Volume 61: Supplement II provides the most up-to-date summation of knowledge of the synthetic chemistry of quinoxalines.

The study of evolution at the molecular level has given the subject of evolutionary biology a new significance. Phylogenetic 'trees' of gene sequences are a powerful tool for recovering evolutionary relationships among species, and can be used to answer a broad range of evolutionary and ecological questions. They are also beginning to permeate the medical sciences. In this book, the authors approach the study of molecular evolution with the phylogenetic tree as a central metaphor. This will equip students and professionals with the ability to see both the evolutionary relevance of molecular data, and the significance evolutionary theory has for molecular studies. The book is accessible yet sufficiently detailed and explicit so that the student can learn the mechanics of the procedures discussed. The book is intended for senior undergraduate and graduate students taking courses in molecular evolution/phylogenetic reconstruction. It will also be a useful supplement for students taking wider courses in evolution, as well as a valuable resource for professionals. First student textbook of phylogenetic reconstruction which uses the tree as a central metaphor of evolution. Chapter summaries and annotated suggestions for further reading. Worked examples facilitate understanding of some of the more complex issues. Emphasis on clarity and accessibility.

A volume in the Chemistry of Heterocyclic Compounds series, this book provides a summary of the chemistry of each of the six naphthyridine systems along with tables of known simple derivatives with original references. Each of the six naphthyridine systems are described in valuable detail and coverage includes: Primary synthetic methods from non-naphthyridine substrates; Chemistry and properties of the parent heterocycle and its simple alkyl derivatives; Formation and reactions of halogeno derivatives; formation and reactions of hydroxy, oxo, alkoxy, and related derivatives.
