Front Cover: Silver‐Catalyzed Direct C6–H Arylation of Purines and Purine Nucleosides with Arylboronic Acids (Eur. J. Org. Chem. 24/2017)

The cover picture shows a silver‐colored statue with a hand holding a triple helix, which can be found at the campus of the Beijing University of Chemical Technology. This DNA‐like statue represents step‐by‐step chemical transformations, in this case the silver‐catalyzed cross‐coupling of purines and aryl boronic acids, shown as different balls at the bottom of the helix, to afford the final C6‐arylated product, shown as the single ball at the top. Details are discussed in the Communication by N. Chen, H. Du et al. on page 3415 ff (https://doi.org/10.1002/ejoc.201700406).
