Original Stereochemical Scenarios for Selective Organocatalysis Dr. Xavier Bugaut

Over the past years, our group has devoted efforts towards the development of new applications of enantioselective organocatalytic Michael additions with β-dicarbonyl substrates. The results obtained following three different research directions will be discussed: (i) the preparation and use of original substrates such as β-ketoaldehydes

[1]

and β-ketoamides;

[2]

(ii) the high synthetic potential of multicomponent reactions to assemble enantioenriched polyheterocyclic products;

[3]

(iii) the preparation of 4-arylpyridine atropisomers through a conversion of chirality strategy.
