Creating a Chemical Space is surprisingly simple: you need building blocks (compounds with functionalizable groups) and reactions (rules for how to combine them).
In advance, you should not worry too much about the number of building blocks or reactions. Due to combinatorics, even a small number of simple reactions already leads to exponential generation of products. Thus, even just a few thousand building blocks can open up trillions of possibilities.
Reactions can be derived from common databases. Alternatively, our
Cookbook offers a selection of proven and robust reactions that can be used as a starting point for further extensions and adaptations.
The generation of the Chemical Space file (.space) is achieved with our tool
CoLibri.
