Highly Diastereoselective Access to Densely Functionalized Piperidine Cores of Influenza Endonuclease Inhibitors via a Metal-Free SN1 Approach

J Org Chem. 2025 Jan 17;90(2):1175-1179. doi: 10.1021/acs.joc.4c02379. Epub 2025 Jan 2.

Abstract

A novel, highly diastereoselective, and metal-free synthesis of multisubstituted piperidines via an SN1 approach is reported in this study. The method allows for the preparation of highly functionalized compounds with exceptional diastereomeric selectivities and consistently reproducible yields. These compounds are of significant interest due to their remarkable biological activities toward influenza endonuclease.
