Abstract

Several chiral polyfunctional ligands were conveniently synthesized from l-amino acids and used to prepare the dinuclear complex in situ. A novel bimetallic catalyst containing dinuclear nickel was developed and applied to the asymmetric Henry reaction. With the assistance of N-methylmorpholine, good enantio­selectivities (up to 91% ee) and moderate yields (up to 72%) were obtained for aryl, heteroaryl, and aliphatic aldehydes. The pathway was air tolerant and easily manipulated, and the reagents were readily available.
