Abstract:

The Michael addition reaction is a powerful synthetic tool to the formation of a new σ C-C bond used in the synthesis of complex organic molecules. Recently, several research groups have focused in the development of this reaction in a selective away. In 2010, Peters et al. described an asymmetric Michael addition between chalcones and azlactones by using Palladium as a catalyst. Thus, in this communication we show our results on a Bronsted acid catalyzed stereoselective Michaeltype addition of azlactones to enones.
