SPRESI database

The SPRESI data collection is one of the largest databases for organic chemistry worldwide. The database covers the scientific literature from 1974 to the present, focusing on organic synthesis. It contains information on 6 millions chemical structures and 3.8 millions chemical reactions abstracted from 627,000 references. The database was jointly built from VINITI (All-Russian Institute of Scientific and Technical Information of the Russian Academy of Sciences, based in Moscow) and ZIC (Zentrale Informationsverarbeitung Chemie, based in east Berlin, up to 1989) and the data are now maintained by the VINITI Institute. Since 1990 [http://www.infochem.de InfoChem GmbH] , based in Munich, Germany, has been the distributor of this data collection.The SPRESI database contains information on organic substances, including coverage of reactions, structures and properties. Over 28 millions of factual data, such as physical properties (boiling/melting points, refractive indexes, etc.), reaction conditions (catalysts, yields, etc.) and keywords have also been abstracted. Links to the literature in which the substances are described are also given.The SPRESI data collection can be accessed online via the web-application [http://www.spresi.com SPRESI^web] , developed and distributed by InfoChem. Alternatively the complete set or subsets of the database can be acquired as raw data in SDF/RDF chemical file format.
