Front Cover Picture: Kinetic Resolution of α‐Silyl‐Substituted Allylboronate Esters via Chemo‐ and Stereoselective Allylboration of Aldehydes (9/2021)

Abstract

The front cover picture, provided by Seung Hwan Cho and co‐workers, illustrates (R)‐TRIP‐catalyzed kinetic resolution of α‐silyl‐substituted allylboronate esters through chemo‐, diastereo‐, and enantioselective allylation of aldehydes. The reaction is proposed to proceed via a chair‐like transition state by the double coordination of (R)‐TRIP to the C−H bond of aldehydes and the oxygen atom of Bpin group, thus effectively resolving α‐silyl‐substituted allylboronate esters with high enantiomeric ratios. Details can be found in the communication by Seung Hwan Cho and co‐workers (J. Park, Y. Jung, J. Kim, E. Lee, S. Y. Lee, S. H. Cho, Adv. Synth.
