Optically Pure C1-Symmetric Cyclic(alkyl)(amino)carbene Ruthenium Complexes for Asymmetric Olefin Metathesis.

We are grateful to the CNRS, the Ecole Nationale Superieure de Chimie de Rennes, the Aix-Marseille Universite, and the University of California San Diego. This work was supported by the Region Bretagne (ARED 2018 “Biometa” N° 601, grant to J.M.), the Agence Nationale de la Recherche (ANR-19- CE07-0017 ChiCAAC, R.J. and M.M.), and the U.S. Department of Energy, Office of Science, Basic Energy Sciences, Catalysis Science Program, under Award DESC0009376 (G.B.). Umicore AG & Co. is acknowledged for a generous gift of ruthenium complexes. M.M. and T.V. thank Shimadzu and Chiral Technology for their support in the separation of chiral molecules by Supercritical Fluid Chromatography (SFC) technology. For computer time, this research used the resources of the KAUST Supercomputing Laboratory (KSL) at KAUST.
