CatSci was tasked with catalyst screening for an asymmetrical hydrogenation of a target.
CatSci was tasked with designing a new bromination method for a key reaction intermediate. Use of bromine rendered the previous process unsuitable for a larger campaign and would require expensive and time-consuming alterations to the plant.
The route supplied by the client involved the use of phenyl cyanate for functionalising a heterocyclic intermediate with a nitrile group. Its ongoing use would require cyanide monitoring, a dedicated waste stream treatment step, and there were concerns over the sourcing of material of appropriate quality over the long term.

CatSci was tasked with the development of a regioselective Buchwald-Hartwig amination for the final bond forming step of an API. The inherited conditions were not robust with respect to reaction conversion leading to stability concerns.
The client's Phase 1 process was struggling to deliver API in low kg qualities. In particular, Intermediate B was of variable quality, and residual metals were known to negatively affect the onward chemistry
CatSci was tasked with performing route-scouting, route selection and early-phase process development over a 6-month period to meet a pilot plant manufacturing slot.
