Front Cover: Induction of Planar Chirality Using Asymmetric Click Chemistry by a Novel Desymmetrisation of 1,3‐Bisalkynyl Ferrocenes (Eur. J. Org. Chem. 43/2019)

Abstract

The Front Cover shows the first use of the new asymmetric CuAAC click reaction to induce planar stereogenicity. Stereodifferentiation in asymmetric induction (in the first CuAAC) and kinetic resolution (in the second CuAAC) are both influenced by (R,R)‐Ph‐Pybox ligands on copper and so both contribute to the observed ees of the chiral monotriazole products. We acknowledge Daniel Starling for graphic design and QuteMol for images of space filling models of Ph‐Pybox which were generated from xyz data obtained by DFT calculations by the authors using Gaussian.
