SUMMARY:Conférence du Professeur Nicolai Cramer (EPFL)
DESCRIPTION:Titre : Teaching Enantioselectivity to C-H Bond Functionalizati
 ons.Cette conférence sera prononcée en anglais par le professeur Nicolai
  Cramer du laboratoire de catalyse et synthèse asymétriques au sein de l
 'École polytechnique fédérale de Lausanne (Suisse). Ce dernier sera à 
 Montréal dans le cadre d'une tournée de conférences en Amérique du Nor
 d.Résumé : Reactions involving the activation and subsequent functionali
 zation of relatively inert C‑H bonds have considerable synthetic potenti
 al because of their economic and ecological benefits. Significant progress
  was made in addressing reactivity and selectivity (mainly chemo- and regi
 o-) issues\, as well as refining mechanistic understanding of the differen
 t pathways. Despite these great advances\, asymmetric transformations have
  so far little precedence.Harsh reaction conditions\, requirement of uncom
 mon\, yet to find ligand systems have hampered developments in this area. 
 The design and development of such new ligands is vital to the success the
 se transformations as the ligand is not only linked to yield and enantiose
 lectivity\, but also impact the reaction outcome itself. The presentation 
 will focus on our recent developments of activating enantiotopic C(sp2)‑
 H and C(sp3)‑H bonds as well as using C‑H activations as entry point f
 or enantioselective downstream reactions. Information supplémentaire
