We are developing flow chemistry methods to extend the synthetic methodology available to our projects. This is having a positive impact on the range of chemistry that we can use in the preparation of libraries for crude reaction mixture screening by SPR. Vernalis has one of the largest Syrris Asia flow chemistry systems in the world. The high precision of the system’s microfluidics allows us to perform “chemistry on a chip” with exceptional control of reaction parameters, such as fine temperature control in both homogeneous and heterogeneous reactions, suitable for design of experiments (DoE) optimisation. We can also automate the synthesis and prepare small compound libraries in 96 well plate format.
In recent publications, high levels of reproducibility have been reported for reactions that have been previously thought of as capricious, or difficult to handle in batch conditions. We have focused on using new methodology for C-C bond forming reactions and we have used flow chemistry to elaborate proprietary compound scaffolds within our medicinal chemistry projects.
We have augmented our flow chemistry capability with state of the art photocatalysis and adapted chemical reactors to maximise surface area and light absorption. This has enabled a wide range of photocatalysed and photoredox reactions.
We can undertake the latest literature electrochemical redox reactions using our IKA Electrasyn 2.0, and are currently investigating the potential of combining electrochemistry with flow. We have expertise in CAD software to design reaction modules, which are then created by 3D printing.
