Kurzfassung:
Parallel synthesis of focused compound libraries for hit confirmation and lead optimization are certainly important drivers for shortening the lead discovery phase in the pharmaceutical and crop protection industries. In this article we show with permission of Roche and Syngenta three
real case studies where Polyphor synthesized focused libraries for lead validation and optimization using high-throughput parallel synthesis and purification techniques. The three examples differ significantly in the synthetic strategies which were employed as well as in the chemical complexity of the final products. A multigeneration approach towards insecticidal triazines, the application of a sequential three-component reaction towards insecticidal and fungicidal thiazoles and finally a multistep synthesis approach of advanced building blocks followed by a two-step final derivatization
towards novel antiviral N-hydroxy-indolin-2-ones are presented. In all cases 100–200 analogues were synthesized using parallel synthesis in solution followed by purification of the final products by parallel flash or high-throughput (unattended) HPLC (coupled to MS) within four months. Promising biological results were obtained in all three cases.
