Solid-phase synthesis is a practical approach for simplifying the time-consuming and routine purification steps in the preparation of numerous synthetic and naturally occurring molecules; however, monitoring such reactions is often challenging due to the lack of a convenient monitoring method. The group of Professor Cheng-Chung Wang (Academia Sinica, Taipei, Taiwan) recently reported a protocol for using thin-layer chromatography in conjunction with a photolabile linker on a resin, resulting in an efficient procedure for monitoring solid-phase reactions in real time.

Professor Wang said: “We have successfully demonstrated that this method enables the monitoring of stepwise chemical transformations, such as glycosylation, peptide esterification, and a copper nanoparticle/cluster-catalyzed click reaction. We hope that this practical technique could be further utilized in various sequential reactions in solid-phase syntheses.”
