Guenther's Presentation(IE only)
Synthetic chemists in today's competitive research environment require fast and easy access to information ranging from new methodologies for the synthesis of new compounds or compound libraries in solution- or solid-phase to the availability of starting materials or new reagents. Fortunately, the amount of information available electronically inhouse or online from large databases combined with data from smaller specialty databases has increased dramatically. But on the other hand, this information becomes increasingly difficult to manage by the enduser chemist. This is a big problem, since retrieval of relevant information about synthetic methodology requires interaction by the chemist in most cases. To alleviate the problem vendors are working to provide improved post-search management of search results, more user-friendly environments and integration with or linking of various data sources. I will discuss the problems inherent in reaction information retrieval and the requirements to facilitate searching for relevant answers to synthetic problems.

CAS has seen a constant increase in the usage of CASREACT since its inception in 1988. With the introduction of SciFinder and SciFinder Scholar, usage of CAS' synthetic information has dramatically increased. As a result, chemists' experience and feedback have led to new capabilities for searching, refining, and analyzing the nearly 4 million reactions included in CASREACT. This talk will focus on the details of the database and the effective use of new features to solve the research problems typically faced by chemists.

This session will focus on the ISI Reaction Center®, which is part of ISI Chemistry®,. The ISI Reaction Center® database delivers information on all new and improved synthetic methods, including comprehensive reaction summaries and more essential conditions than can be found in any other large reaction database. No other single reaction database is as comprehensive or covers as long of a time span - from the 1840s to the present. Researchers can track the development of advances and better understand the basic research that made today's breakthroughs possible.
Updated monthly, Reaction Center covers over 250 international journals and new synthetic methods reported in patent literature. Coverage includes several areas of chemistry, including different areas of organic and bioinorganic chemistry as well as biochemistry. Also, because the reactions are indexed by type, it's easy to identify special classes such as solid-phase syntheses. Historical data places a special emphasis on heterocyclics, steroids, carbohydrates, peptides and nucleosides.
This talk will outline the key features of the available data as well as the versatile ways that information can be retrieved and catalogued. Newly enhanced exporting features which allow rapid retrieval of pertinent reactions from previous searches including direct URL linking to the desired article or downloads of specific reactions via RDfiles for use with in-house databases will also be discussed.

Guido's Presentation(IE only)
The talk describes the development of an integrated electronic system for the generation of chemical information, the evaluation procedures and the user software of Science of Synthesis, Houben-Weyl Methods of Molecular Transformations. The series METHODEN DER ORGANISCHEN CHEMIE (Houben-Weyl Methods of Organic Chemistry) was established in 1909. The comprehensive description of preparative methods in a consistent style and their critical evaluation by leading experts is the philosophy on which Houben-Weyl was founded. Facing dramatic developments in chemistry during the last few decades which have provided chemists with a wealth of new reagents and reactions, the need for a new, comprehensive, and critical treatment of synthetic chemistry has become apparent. This new edition is entitled Science of Synthesis, Houben-Weyl Methods of Molecular Transformations and is edited by D. Bellus (Switzerland), S. V. Ley (UK), R. Noyori (Japan), M. Regitz (Germany), P. J. Reider (USA), E. Schaumann (Germany), I. Shinkai (Japan), E. J. Thomas (UK), and B. M. Trost (USA). Science of Synthesis will benefit from more than 90 years of experience and will continue the tradition of excellence in publishing organic chemistry reference works. It will offer a truly comprehensive, critical treatment of synthetic organic and organometallic chemistry. Science of Synthesis will cover the whole field of organic chemistry based on all published and readily available sources from the early 1800s until the year of publication. Authors will provide chemists with the most reliable methods to solve their synthesis problems. For each method a detailed experimental procedure will be included. To best meet the needs of the scientific community, Science of Synthesis will be published as an electronic version and also in print (http://www.science-of-synthesis.com). The electronic version is being developed under the guidance of an advisory board comprising A. Barth (Germany), G. Baysinger (USA), A. Mullen (Germany), H. Rzepa (UK), and E. Zass (Switzerland).

The number of reactions available through electronic access has risen to over 10 million. Yet the problem still remains on how best to retrieve the relevant reactions from this large collection and how to analyze the information present in these retrieved reactions so as to quickly get back to the problem at hand carrying out the desired synthesis in the laboratory.
Ways to facilitate reaction retrieval will be discussed. Improvements in indexing reactions provide the necessary infrastructure to access the information and enhancements to reaction searching applications, particularly in the user interface, enable the synthetic chemist to more easily navigate within the information presented by reaction databases and efficiently make decisions.Comments to:
