✦ Synopsis

The imines 4 containing a diphenylcarbinol moiety serve as chiral ligands in novel enantiomerically pure imine-alkoxytitanium(IV) complexes. Depending on the molar ratio of the starting materials, imines 4 and titanium tetraisopropoxide, mono-chelated complexes 5 or bis-chelated complexes 6/7 result. The latter are formed diastereoselectively and the iso-
