Abstract
The first reported cubane-based chiral Schiff base ligand has been successfully synthesized. This ligand has been evaluated on the nitro-aldol (Henry) reaction. The reactions were performed in the presence of four different copper salts, using eight different solvents, and five different temperatures. The highest enantioselectivity obtained for this novel ligand was ˜39% ee.
