The main purpose of this PhD thesis was the development of new enantioselective organocatalyzed reactions involving bifunctional catalysis if possible by means of ion-pairing catalysts. Firstly, this approach was applied to the nucleophilic dearomatization of pyridinium salts based upon an original bifunctional system ion pair/enamine. The 1,4-dihydropyridines were obtained with good regioselectivity albeit in low yields and enantiomeric excesses (19% yield and 32% ℯℯ max). Thereafter, a one-pot organocatalysed deracemization reaction of ketones bearing a stereogenic center at their α position was studied. The first step relied on a silyation reaction to provide a silyl enolate which was in the second step, submitted to an enantioselective ...
