Search for chiral catalysts through ligand diversity: Substrate-specific catalysts and ligand screening on solid phase

, p. 1704 - 1707 (1997)
An efficient strategy in the search for chiral catalysts is ligand optimization on solid support. This diversity approach provides unique opportunities for the identification of substrate-specific catalysts and leads to the discovery of ligands with unusu
Enantiotopic Discrimination by Coordination-Desymmetrized meso-Ligands
Li, Yutang,Lidskog, Anna,Armengol-Relats, Helena,Pham, Thanh Huong,Favraud, Antoine,Nicolas, Maxime,Dawaigher, Sami,Xiao, Zeyun,Ma, Dayou,Lindb?ck, Emil,Strand, Daniel,W?rnmark, Kenneth

The first examples of enantiopure catalysts that are chiral merely due to coordination of different metal ions at enantiotopic positions of an achiral meso-ligand are reported. These catalysts exhibit a pseudo-Cs symmetry and are able to catalyze reactions demanding simultaneous involvement of two catalytic sites. The latter was demonstrated by application in the asymmetric ring-opening of meso-epoxides.
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.

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
