Asymmetric addition of aryllithiums to naphthalene BHA-esters catalyzed by a chiral ligand

Article abstract of DOI:10.1016/S0040-4039(00)61651-9

In the presence of both stoichiometric and catalytic amounts of a chiral dieter 1, aryllithiums reacted with BHA-esters of naphthalenecarboxylic acids 2, 5 to afford the corresponding adducts 4, 6 in high ee.
