Resumen

The reaction between N-acryloyl-N-methyl-L-alanine methyl ester and cyclopentadiene is studied. The configuration of the cycloadducts preferably obtained depends on the reaction conditions and the Lewis acid used as a catalyst. In TiCl4-catalyzed reactions, high exo:endo ratios and good diastereomeric excesses in exo cycloadducts are obtained under several conditions. So an interesting method for the asymmetric synthesis of derivatives of exo- norbornane-2-carboxylic acid is described.
