The development of enantioselective catalytic processes for the manufacture of chiral intermediates is a very complex endeavor and can be very time consuming and expensive. In this contribution the major issues which might lead to long development times will be discussed and strategies to deal with these problems are described. The general part is illustrated with the approach Solvias has chosen for assisting and supporting the development of enantioselective homogeneous hydrogenation processes, at the moment the most important industrial application of asymmetric catalysis. Special emphasis is given to the application of high-throughput screening (HTS) using a Symyx HiP system and the description of the Solvias portfolio of chiral ligands which makes a broad variety of diphosphine ligands available for all phases of process development from the first screening experiments to the large-scale manufacturing phase. Four case histories serve to illustrate the generic description of the development process.
