SYNLIB reaction retrieval system

On the other hand, the data in the base file may be converted into an SMD file (Standardised Molecular Data) which is used by the companies of the CASP pool in Europe for interchanging substance and reaction data. Interfaces to commercially available reaction retrieval systems, using the SMD data structure, exist or are being developed. In this way, in-house versions of the database to be used with REACCS, ORAC, SYNLIB, etc., will be made available. 

SYNLIB is a very special reaction retrieval system, which differs significantly from other systems in terms of the underlying philosophy and functionality. It has a built-in fuzziness, such that usually not the entire (sub)structures entered are matched in the database, but only those parts of the query that the user declared as target (Figure 10). Target centers are usually reaction centers plus some parts of the environment . " ... 

This technique can be used to search the public literature, to retrieve the "hesV literature precedents for a desired reaction. The search question can be generally formulated as Which possibilities are available to convert starting material P into target material T Systems to answer this question are SYNLIB, ORAC and REACCS. 

Reaction-oriented searching can also be used as an in-house tool to store and retrieve company reactions. The DARC-RMS and MACCS/REACCS systems are typical examples of this usage, although SYNLIB and ORAC could alsobe used for this purpose.
