摘要：

A set of aromatic, aliphatic and alpha,beta-unsaturated aldehydes has been asymmetrically trimethylsilylcyanated with e.e.'s ranging from 40% to 80% using a chiral (salen)Ti(IV) catalyst prepared in situ from titanium tetraisopropoxide and (1R,2R)[N,N'-bis(2'-hydroxy-3'-t-butyl-benzylidene)]-1,2-diaminocyclohexane or (1R,2R)-[N,N'-bis(2'-hydroxybenzylidene)]-1,2-diaminocyclohexane.
