Facile Synthesis of C2-Symmetric Tridentate Bis(thiazoline) and Bis(oxazoline)
and their Application in the Enantioselective Henry Reaction. — A vari11- 080 Ligands
ety of bis(thiazoline) (I) and bis(oxazoline) (II) ligands is prepared and tested in the
asymmetric Henry reaction. Generally, best results are achieved with Cu(O-Tf)2 as catalyst, while the opposite enantiomer of the product is formed in the presence of
Zn(O-Tf)2. The yield and enantioselectivity is influenced by the substitution pattern of
the ligand but no clear trend is to be seen. — (LU, S.-F.; DU*, D.-M.; ZHANG, S.-W.;
