InfoChem's ICSYNTH is a powerful computer aided synthesis design tool that enables chemists to generate synthetic pathways for a target molecule. The benefit is that ICSYNTH can facilitate innovation by stimulating ideas for alternative or novel synthetic routes that otherwise may not be considered. This may lead to improved route design, for example shorter pathways or more economical reaction modifications.

After inputting the target, users can select different synthetic strategies depending on requirements. ICSYNTH then automatically generates a multistep interactive synthesis tree – each node on the tree representing a precursor. The advantages are that the suggested reactions are based on, and linked to, published reactions (or their analogs) and the precursor availability is automatically checked in commercial catalogs. Users can modify the synthesis tree or select precursors for further analysis.

At the heart of ICSYNTH is an algorithmic chemical knowledge base of transform libraries that are automatically generated from reaction databases. The number of transform libraries is only limited by the availability of validated reaction databases.
A significant advantage of ICSYNTHs concept is the possibility of generating rapidly and straightforwardly in-house libraries of transforms based on companies’ proprietary and confidential reaction data (e.g. ELNs), for private use in their own ICSYNTH installations.
Many new features have been deployed in version 3.1, launched in October 2017. First of all a simplyfied query submission form has been added to the well-known expert one, enabling first-time users to draw a molecule and start a retrosynthetic analysis based on fixed sets of parameters. In addition, visualization of the results has been enhanced: comparison of two different trees for the same target molecule, displaying for example their union or intersection, is now possible. Grouped precursors can be now viewed and expanded in the tree, whithout having to open the extra cluster window and smooth switching between reaction graph and tree view has also been integrated. Furthermore, export features have been improved: selected pathways can be exported in different formats (xls and rdf), as well as reactions contained in a specific cluster.

How does it work?

ICSYNTH takes advantage of the automatic generation of chemically meaningfull precursors from accredited reaction databases (license required), such as:

The transform libraries produced during the automatic process are the basis for the chemical knowledge of the software.
Furthermore, a direct link from the suggested transformation to the original reaction described in the literature enables the user to decide if the proposed synthesis path is acceptable.
