Abstract
C2-dissymmetric PyOX-ligands have been applied to the asymmetric Henry reaction. This widely applicable reaction is easy to perform, requires no inert atmospheres or dry solvents, and gives good selectivities. By adjusting ligand side-chains, a significant impact on selectivities was observed.
