摘要：

The enantioselective addition of dialkylzinc to several aldehydes, using different chiral bidentate ligands (3a-j, 4a-h) [derived from (+)-10-camphorsulfonyl chloride] and titanium alkoxide as catalysts, is studied. The influence of temperature, titanium alkoxide, stoichiometry, additive, aldehyde and ligand structure is also studied. (C) 1997 Elsevier Science Ltd.
