Enantioselective Synthesis and Biological Evaluation of Pyrrolidines Bearing Quaternary Stereogenic Centers.

Molecular complexity plays an increasingly important role in the modern pharmaceutical industry. Setting up multiple stereogenic centers in privileged substructures may give rise to improved or even unprecedented bioactivities; however, this area remains largely unexplored due to the tremendous synthetic challenges. Herein, we report a series of multisubstituted pyrrolidines with four continuous stereogenic centers, including up to two aza-QSCs (quaternary stereogenic centers). Systematic evaluations, including phenotypic screening, molecular docking, molecular dynamics, bioinformatics, and bioactivity analysis, have been performed to screen entities with pharmacological properties of interest. Among them, compound 4m with two QSCs was identified to be a potent antiproliferation agent through disturbing mitosis exit, and the presence of QSCs was found to be crucial for anticancer efficacy. This work illustrates that the introduction of QSCs in privileged scaffolds not only helps to expand the unpatented chemical space but also provides new opportunities for the discovery of novel therapeutic agents.
