Front Cover: Polystyrene-Supported Aminocatalyst Derived from Diarylprolinol for Asymmetric ?-Amination of Aldehydes (Eur. J. Org. Chem. 21/2023)

The Front Cover illustrates the natural environment that needs to be protected by following the principles of 3Rs (Reduce, Reuse, and Recycle). The background of the picture shows our institute's riverfront, where a reusable polymer-supported aminocatalyst was developed for the sustainable synthesis of chiral amino acid derivatives. Cover design by Ms. Gayathri Chandrakumar. More information can be found in the Research Article by C. Appayee et?al.
