Asymmetric ring opening of epoxides with cyanides catalysed by chiral binuclear titanium complexes

Maleev, Victor I.,Chusov, Denis A.,Yashkina, Lidiya V.,Ikonnikov, Nikolai S.,Il'In, Michail M.

, p. 838 - 843 (2014/06/23)

A series of Schiff bases obtained from salicylaldehydes and 3,3′-diformyl-BINOL were synthesized. The complexes of these Schiff bases with Ti(IV) were active for the asymmetric ring opening of epoxides with TMSCN. A mixture of unpurified ligands was found
