Abstract
A new type of Salen ligands derived from (2R, 3R)-N-benzyl-2,3-diaminopyrrolidine and aromatic hydroxyaldehydes was synthesized and tested in the enantioselective alkylation of aromatic aldehydes with diethylzinc, moderate selectivity being observed. This study represents the application of a new type of Zn- Salen ligands and opens the way to exploring these promising new structures in other enantioselective and biological processes.
Keywords: Pyrrolidine, diamine, Salen, diethylzinc, enantioselective, alkylation
