| Abstract: | A family of titanium(IV) alkoxo compounds {Ti(O‐i‐Pr)2(OR)2}2] 1–4 prepared by alcohol exchange of Ti(O‐i‐Pr)4 and a chiral higher‐boiling alcohol ROH = 1,2:3,4‐di‐O‐isopropylidene‐α‐d ‐galactopyranose, 1,2:5,6‐di‐O‐isopropylidene‐α‐d ‐glucofuranose, (1R,2S,5R)‐(?)‐menthol, (1S‐endo)‐(?)‐borneol, (1S,2R,5S)‐(+)‐menthol, and (+)‐borneol] has been tested to evaluate their catalytic activity and stereoselectivity in the asymmetric epoxidation of cinnamyl alcohol. © 2005 Wiley‐Liss, Inc.
