The in situ formed Ti(IV) complexes of pyrrolidine-based chiral salen ligands derived from natural l-tartaric acid were evaluated as catalysts in the enantioselective trimethylsilylcyanation of aromatic aldehydes. The different activity and selectivity of the catalysts in the formation of the products were found to be dependent on the N-substituent of the pyrrolidine.
Enantioselective syntheses of trans-3,4-difluoropyrrolidines and investigation of their applications in catalytic asymmetric synthesis

, p. 9771 - 9779 (2007/10/03)
Asymmetric syntheses of enantiopure trans-3,4-difluoropyrrolidines have been prepared by the introduction of fluorine at both centers in a single operation; asymmetric epoxidations and additions to benzaldehyde were conducted using catalysts whose chirality depends on organofluorine asymmetry.
The first enantioselective syntheses of vicinal difluoropyrrolidines and the first catalytic asymmetric synthesis mediated by the C2 symmetry of a -CHFCHF- Unit
Marson, Charles M.,Melling, Robert C.
, p. 1223 - 1224 (2007/10/03)
The first enantiopure vicinal difluorides of C2 symmetry have been prepared by the introduction of fluorine at both centres in a single operation; the first asymmetric synthesis using a catalyst whose chirality depends on organofluorine asymmetry is described.
