Abstract:
Enantioselective dicarbofunctionalization of alkenes is a powerful strategy for constructing functionalized sp³-rich molecules, yet it remains challenging for unactivated substrates lacking directing groups. While asymmetric multicomponent reactions catalyzed by d¹⁰ transition metals have advanced for activated alkenes, enantioselective multicomponent cross-coupling of unactivated alkenes, particularly enabling remote functionalization to stereoselectively generate the nonadjacent stereocenters, is still underdeveloped. Herein, we report a palladium-catalyzed asymmetric migratory dicarbofunctionalization of directing-group-free, trisubstituted unactivated alkenes. This method forges remote stereogenic centers, enabling both 1,3-diarylation and 1,4-diarylation with high enantioselectivity and diastereoselectivity. Mechanistic studies indicate a chain-walking process involving irreversible Pd-H migration, rationalizing the observed regiocontrol.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...

Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.
