   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Organic chemistry; Catalysis; Asymmetric; Hydrogenations; Reductions; Alkenes; Imines; Vinyl fluorides; Enolphosphinates; Transition metal; Complexes; Iridium; Organisk kemi; Chemistry; Kemi;

   Sammanfattning : The research described in this thesis is directed toward the efficient, enantioselective synthesis of chiral products that have useful functionality. This goal was pursued through catalytic asymmetric hydrogenation, a reaction class that selectively introduces one or two stereocenters into a molecule in an atom-efficient step. LÄS MER
