Abstract
The Rh-catalyzed, substrate directed catalytic asymmetric hydroboration of γ,δ-unsaturated amides provides a direct route to enantioenriched acyclic secondary γ-borylated carbonyl derivatives with high regio- and enantioselectivity. The catalytic condition optimization and substrate scope study is discussed, including the effects in catalytical asymmetric hydroboration on pre-installed chiral γ,δ-unsaturated amides. A mechanistic study from kinetic approach by graphical manipulation (reaction progress kinetic analysis for substrate orders and normalized time analysis for catalyst order.) was discussed in this thesis
