摘要：

The chiral diamine ligand 3 was designed and synthesized from (R,R)-1,2-diphenylethylenediamine, (S)-2,2'-dibromomethyl-1,1'-binaphthalene, and o-xylylene dibromide. The resulting 3-Cu(OAc)(2) complex was a highly efficient catalyst for the Henry reaction, giving the various nitroaldols with over 90% ee (up to > 99%). The reaction was performed in n-propyl alcohol at room temperature, and the Henry adducts were produced in high yield with excellent enantiomeric excess; these attributes are desirable in a catalyst for practical use.
