  The synthesis of tetradentate salens derived from (3R,4R)-N-substituted-3,4-diaminopyrrolidines and their application in the enantioselective trimethylsilylcyanation of aromatic aldehydes

  摘要：

  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. (C) 2013 Elsevier Ltd.

  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.

  通过在一次操作中在两个中心引入氟，制备了第一个 C2 对称的对映体纯邻位二氟化物；描述了使用其手性取决于有机氟不对称性的催化剂的第一个不对称合成。
