Which way? Palladium thiourea catalyzed Pauson-Khand reaction of norbornene with substituted alkynoates to afford selectively either α-carboxylated adducts or β-carboxylated adducts with the reverse regioselectivity has been demonstrated for the first time. Control of the regioselectivity in this transformation is governed by the addition of LiCl. A mechanistic interpretation to account for this observed regioselectivity is presented.
