Wiley & Sons Ltd
Short Description
In the past decade, completely new perspectives have been developed for the use of azides in peptide chemistry, combinatorial chemistry, and heterocyclic synthesis. The world-ranked authors of Organic Azides describe their own research in the wider context of azide chemistry and include a vital chapter on safe synthesis and handling. This first state-of-the-art overview of this important class of compounds will be of vital interest to organic chemists, drug discovery researchers, materials scientists and those interested in the chemistry of natural products.
* Most current state-of-the-art overview of this important class of compounds, encompassing many new and emerging applications
* The number of articles on organic azides continues to increase tremendously; on average, there are more than 1000 new publications a year
* Covers basic chemistry as well as state-of-the-art applications in life science and materials science
* World-ranked authors describe their own research in the wider context of azide chemistry
* Includes a chapter on safe synthesis and handling (azides can decompose explosively)
