✦ Synopsis

Remarkable Effect of Basic Ligands in the Lanthanoid-Catalyzed Enantioselective Cycloadditions of 3-Carbomethoxy-2-pyrone (3-CMP).

-The enantioselectivity of the Yb-catalyzed asymmetric Diels-Alder reaction of pyrone (I) and the electron-rich olefins (II) is remarkably enhanced by addition of oxygen nucleophiles such as THF, tBuOH or water.
