Organometallic compounds reactions with imines

One of the most studied imine precursors in the reaction with organometallic compounds is (3R,4R)-4-acetoxy-3-[(R)-l -((t-butyldimethylsilyl)oxy)ethyl]-2-azetidinone (31) (equation 23)97. 

Precursor of Useful Chiral Ligands. OPEN is widely used for the preparation of chiral ligands. Organometallic compounds with these ligands act as useful reagents or catalysts in asymmetric induction reactions such as dihydroxylation of olefins, transfer hydrogenation of ketones and imines, Diels-Alder and aldol reactions, desymmetrization of meso-diols to produce chiral oxazolidinones, epoxidation of simple olefins, benzylic hydroxylation, and borohydride reduction of ketones, imines, and a,p-unsaturated carboxylates. ... 

Reactions with BucNC lead to new organometallic compounds containing an 72-C,N-bound cyclopentadiene imine, which was structurally characterized as a pyridine adduct (Scheme 118). Reactions with benzonitrile lead to the elimination of 1 equiv. of the corresponding pyridine and formation of the dimeric titanium derivative (ArO)2Ti(/x-PhCN)2Ti(OAr)2 containing two bridging benzonitrile ligands. The compound has been structurally characterized...
