Resumo

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, (1 R ,2 S ,5 R )‐(−)‐menthol, (1 S ‐ endo )‐(−)‐borneol, (1 S ,2 R ,5 S )‐(+)‐menthol, and (+)‐borneol] has been tested to evaluate their catalytic activity and stereoselectivity in the asymmetric epoxidation of cinnamyl alcohol. © 2005 Wiley‐Liss, Inc.
