Song, Qingbao published the artcileCatalytic asymmetric Henry reaction using copper(II) chiral tridentate Schiff-base complexes and their polymer-supported complexes, Recommanded Product: 5-Bromo-3-chloro-2-hydroxybenzaldehyde, the publication is Comptes Rendus Chimie (2015), 18(2), 215-222, database is CAplus.
A series of chiral tridentate Schiff-base ligands and their polymer-supported ligands were conveniently prepared and introduced as copper(II) chiral complexes for the asym. Henry reaction. The structures of these ligands have been characterized by IR, 1H NMR, 13C NMR and MS. The exptl. results showed that the corresponding β-nitro alcs. were obtained in moderate to high yields (up to 98%) with up to 98% ee under mild conditions. The complex catalyst forming from copper(II) polymer-supported ligands could be recycled by a simple filtration and reused 6 times at least with similar good catalytic effect (about 94% yield and 90% ee).
