Pharmaceutical Substances is a first point of reference or any person wishing to screen information about drugs. It provides a compendium of more than 2400 active pharmaceutical ingredients (APIs) of interest to the chemical and pharmaceutical industries. Since the work was fi rst published in the 1970s the focus of the product has remained unchanged: Professors Axel Kleemann, Jürgen Engel, Bernhard Kutscher, and Dr. Dietmar Reichert present in a clear and concise manner highly evaluated information collected from all the relevant literature, and commercial patent data. This includes synthetic routes and all intermediates for newly approved drugs from the six most important markets. For more than 30 years, Pharmaceutical Substances has been an authoritative resource for everyone involved in design, discovery, development, evaluation, and marketing of drugs. The now structure searchable online version is updated biannually and is the most advanced incarnation of this unique reference to every API of significance.

Science of Synthesis

A truly authoritative online resource, Science of Synthesis offers comprehensive and indepth coverage of synthetic organic chemistry. This work is designed to be the first point of reference for chemists searching for reliable synthetic methods.

Science of Synthesis focuses on the most effective and reliable methods for functional group transformations, and imparts essential reviews as well as detailed experimental procedures. Under the guidance of an international Editorial Board composed of distinguished chemists with unparalleled experience, over 1000 authors are contributing to the 48 volumes of Science of Synthesis. The volume editors and authors, who are leading experts in their respective fields, evaluate all the literature of relevance including the vast amount of primary literature available to modern researchers. The contributions are presented in Science of Synthesis in the form of highly evaluated digests for each field of synthetic organic chemistry. New content is added to Science of Synthesis on a regular basis with up to seven volumes per year being published. The series is set for completion in 2008 and will then contain over 18 000 generally applicable experimental procedures, 240 000 reactions and 800 000 structures. The methods in Science of Synthesis are complemented by additional material contained within the unique electronic backfile, containing every volume published in the HoubenWeyl series 19092003. The backfile includes a further 146 000 experimental procedures that cover synthetic knowledge stretching back to the late 1800s. Science of Synthesis brings the experts perspective and knowledge into the laboratory and provides access to 100 years of scientific endeavor in synthetic organic chemistry.
